A 0.050 kg toy truck moving right at 0.20 m/s collided with a toy car weighing 0.015 kg initially at rest, on a frictionless track. The truck keeps moving right at 0.15 m/s after the collision,
what is the final speed of the race car?
Answer:
0.1667 m/s
Explanation:
m1V1 + m2V2 = m1V3 + m2V4
0.01 = ( 0.0075) + (0.015 * V4)
V4 = (0.01 - 0.0075) / (0.015)
V4= 0.1667
Answer:
0.167 m/s

how does the index of refraction of an unknown substance compare to the index of refraction of a vacuum? explain how the speed and the refraction of light would behave in both?
Answer:
By measuring the speed of light in both in space and that unknown substance
Explanation:
Refractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density.
By measuring the speed of light in that medium and dividing it by speed of light 3*10^8 we can measure the refractive index of any medium
car 1 is traveling south at 18 m/s and has a full load, giving it a total mass of 14,650 kg. Car 2 is traveling north at 11 m/s and has a mass of 3,825 kg. After the collision, car 1 has a final velocity of 6 m/s south. What is the velocity of car 2
Answer:
v_{4}= 80.92[m/s] (Heading south)
Explanation:
In order to calculate this problem, we must use the linear moment conservation principle, which tells us that the linear moment is conserved before and after the collision. In this way, we can propose an equation for the solution of the unknown.
ΣPbefore = ΣPafter
where:
P = linear momentum [kg*m/s]
Let's take the southward movement as negative and the northward movement as positive.
[tex]-(m_{1}*v_{1})+(m_{2}*v_{2})=-(m_{1}*v_{3})+(m_{2}*v_{4})[/tex]
where:
m₁ = mass of car 1 = 14650 [kg]
v₁ = velocity of car 1 = 18 [m/s]
m₂ = mass of car 2 = 3825 [kg]
v₂ = velocity of car 2 = 11 [m/s]
v₃ = velocity of car 1 after the collison = 6 [m/s]
v₄ = velocity of car 2 after the collision [m/s]
[tex]-(14650*18)+(3825*11)=(14650*6)-(3825*v_{4})\\v_{4}=80.92[m/s][/tex]

Analyze the chemical reaction below
16 g CH4 + 64 g O2 → 44 g CO2 + 36g H2O
Explain the law of conservation of mass and describe how the equation represents the law of conservation of mass.
Answer:
Explanation:
The law of conservation of mass states that the mass of the elements at the beginning of the reaction(reactants) will equal the mass at the end of the reaction (product) .
In the chemical equation above,the total mass of the reactants is 80g(16+64) and the total mass of the products is also 80g(44+36).therefore the mass remained constant and that's how the equation represents the law of conservation of mass

A student is helping his teacher move a 40.0 kg aquarium. What net sideways force must he exert on the aquarium to slide it across the floor so that it accelerates at 0.50 m/s2?
Answer:
20 N
Explanation:
From the question given above, the following data were obtained:
Mass (m) of aquarium = 40 kg
Acceleration (a) = 0.50 m/s²
Force (F) =?
Force is simply defined as the product of mass and acceleration. Mathematically, it is expressed as:
Force (F) = mass (m) × acceleration (a)
F = m × a
With the above, we can obtain the force needed to slide the aquarium as follow:
Mass (m) of aquarium = 40 kg
Acceleration (a) = 0.50 m/s²
Force (F) =?
F = m × a
F = 40 × 0.5
F = 20 N
Therefore, a force of 20 N is needed to slide the aquarium.
During a thunderstorm a tornado lift a car to a height of 300 m above the ground increasing and strength the tornado flings the car horizontally with the speed of 80.0 m/s how long does the car take to reach the ground how far horizontally does the car travel before hitting the ground
Answer:
Explanation:
To calculate the time it took the car to hit the ground, we use the formula
speed = distance/time
80 m/s = 300 m/time
time = 300/80
time = 3.75 secs
It must have taken the car 3.75 seconds to hit the ground
To determine the horizontal distance of the car before hitting the ground, the same formula will also be used but with the time obtained above (since that was the time it took before hitting the ground)
speed = distance/time
80 = distance/3.75
distance = 3.75 x 80
distance = 300 meters

A jet liner must reach a speed of 82 m/s for takeoff. If the
runway is 1500 m long, what acceleration must the jet
have?
Answer:
The acceleration that the jet liner that must have is 2.241 meters per square second.
Explanation:
Let suppose that the jet liner accelerates uniformly. From statement we know the initial ([tex]v_{o}[/tex]) and final speeds ([tex]v_{f}[/tex]), measured in meters per second, of the aircraft and likewise the runway length ([tex]d[/tex]), measured in meters. The following kinematic equation is used to calculate the minimum acceleration needed ([tex]a[/tex]), measured in meters per square second:
[tex]a = \frac{v_{f}^{2}-v_{o}^{2}}{2\cdot d}[/tex]
If we know that [tex]v_{o} = 0\,\frac{m}{s}[/tex], [tex]v_{f} = 82\,\frac{m}{s}[/tex] and [tex]d = 1500\,m[/tex], then the acceleration that the jet must have is:
[tex]a = \frac{\left(82\,\frac{m}{s} \right)^{2}-\left(0\,\frac{m}{s} \right)^{2}}{2\cdot (1500\,m)}[/tex]
[tex]a = 2.241\,\frac{m}{s^{2}}[/tex]
The acceleration that the jet liner that must have is 2.241 meters per square second.
Use the computational model of a cannon and cannonball shown to answer the question below.
If the mass of the cannonball increases, and all other initial conditions stay the same, what would happen to the velocity and kinetic energy of the cannonball?
A. The velocity decreases, and the kinetic energy decreases.
B. The velocity decreases, and the kinetic energy increases.
C. The velocity increases, and the kinetic energy decreases.
D. The velocity increases, and the kinetic energy increases.
Answer:
It would be option B.
Explanation:
Option B. is the right answer because as the mass of the canon increases the kinetic energy will increase as well, but the will decrease due to its greater mass.
If the mass of the cannonball increases, and all other initial conditions stay the same, the velocity decreases, and the kinetic energy increases.
The kinetic energy of an object is the energy possessed by the object due to its motion.
[tex]K.E = \frac{1}{2} mv^2[/tex]
where;
m is the mass of the objectv is the velocity of the objectK.E is the kinetic energy of the objectWhen the mass increases, the kinetic energy will increase.
[tex]v^2 = \frac{2K.E }{m}\\\\v=\sqrt{\frac{2K.E }{m}}[/tex]
when the mass increases, the velocity of the cannonball will decrease.
Thus, we can conclude that if the mass of the cannonball increases, and all other initial conditions stay the same, the velocity decreases, and the kinetic energy increases.

Two 5.0-kg carts collide on a one-dimensional air track. The total momentum of the carts was 4.9 kg m/s rightwards before the collision. After the collision, one cart is moving leftwards at 0.15 m/s. what is the velocity of the second cart?
Answer:
1.13 m/s right
Explanation:
Momentum before = momentum after
p₀ = p
p₀ = m₁ v₁ + m₂ v₂
4.9 kg m/s = (5.0 kg) (-0.15 m/s) + (5.0 kg) v
4.9 kg m/s = -0.75 kg m/s + (5.0 kg) v
5.65 kg m/s = (5.0 kg) v
v = 1.13 m/s
Answer: 1.13 m/s equivalent to 1.1 m/s

A block slides down a 30.0 degree inclined plane at an acceleration of 2.0 m/s^2. What is the coefficient of friction between the block and the inclined plane? Use g=10.0 m/s^2
A) .20
B) .25
C) .30
D) .35
Answer:
D) .35
Explanation:
m = Mass of block
g = Acceleration due to gravity = [tex]10\ \text{m/s}^2[/tex]
[tex]\theta[/tex] = Angle of inclination = [tex]30^{\circ}[/tex]
a = Acceleration of block = [tex]2\ \text{m/s}^2[/tex]
[tex]\mu[/tex] = Coefficient of friction between the block and the inclined plane
f = Frictional force = [tex]\mu mg\cos\theta[/tex]
As the forces are conserved in the system we have
[tex]mg\sin\theta-f=ma\\\Rightarrow mg\sin\theta-\mu mg\cos\theta=ma\\\Rightarrow g(\sin\theta-\mu\cos\theta)=a\\\Rightarrow \sin30^{\circ}-\mu\cos30^{\circ}=\dfrac{2}{10}\\\Rightarrow \dfrac{1}{2}-\mu\dfrac{\sqrt{3}}{2}=0.2\\\Rightarrow \mu=\dfrac{\dfrac{1}{2}-0.2}{\dfrac{\sqrt{3}}{2}}\\\Rightarrow \mu=\dfrac{0.3\times 2}{\sqrt{3}}\\\Rightarrow \mu=0.3464\approx 0.35[/tex]
The coefficient of friction between the block and the inclined plane is 0.35

Determine the activity of the sample of cerium when the sample was 20 seconds old
Answer:
There are [tex]3.779\times 10^{23}[/tex] atoms when the sample of cerium is 20 seconds old.
Explanation:
The decay of isotopes is modelled after the following exponential expression:
[tex]N(t) = N_{o}\cdot e^{-\left(\frac{\ln 2}{t_{1/2}}\right)\cdot t }[/tex] (1)
Where:
[tex]N_{o}[/tex] - Initial number of atoms, dimensionless.
[tex]N(t)[/tex] - Current number of atoms, dimensionless.
[tex]t[/tex] - Time, measured in seconds.
[tex]t_{1/2}[/tex] - Half-time, measured in seconds.
Now we clear the half-time within (1):
[tex]\ln \frac{N(t)}{N_{o}} = -\frac{t\cdot \ln 2}{t_{1/2}}[/tex]
[tex]t_{1/2} = -\frac{t\cdot \ln 2}{\ln \frac{N(t)}{N_{o}} }[/tex]
If we know that [tex]N_{o} = 5\times 10^{23}[/tex], [tex]N(t) = 2\times 10^{23}[/tex] and [tex]t = 66\,s[/tex], then the half-life of the isotope is:
[tex]t_{1/2}=-\frac{(66\,s)\cdot \ln 2}{\ln \frac{2}{5} }[/tex]
[tex]t_{1/2}\approx 49.927\,s[/tex]
And the decay equation for the sample is described by:
[tex]N(t) = (5\times 10^{23})\cdot e^{-0.014\cdot t}[/tex]
Lastly, if we get that [tex]t = 20\,s[/tex], then the activity of the sample of cerium is:
[tex]N(20) = (5\times 10^{23})\cdot e^{(-0.014)\cdot (20)}[/tex]
[tex]N (20) \approx 3.779\times 10^{23}[/tex]
There are [tex]3.779\times 10^{23}[/tex] atoms when the sample of cerium is 20 seconds old.

Four directional arrows with labels five hundred seventy-nine Newtons, four hundred eighty-seven Newtons, five hundred seventy-nine Newtons and six hundred thirty-two Newtons
Objects change motion due to forces. When they become unbalanced, their motion changes, while balanced forces cause constant motion. Unbalanced forces result in a change of velocity. What is it called when velocity changes?
Answer:
Balanced forces: When a number of forces acting on a body do not cause any change in its state of rest or of uniform motion along a straight line then the forces are said to be balanced forces. In other words, a body is said to be underbalanced forced when the resulting force acting on the body is zero.
The balanced forces:
⋅ Cannot set any stationary body into motion.
⋅ May change the shape and size of soft objects.
⋅ Cannot change the speed/velocity of a moving body.
Unbalanced forces:
When the resultant of all the forces acting on a body is not zero, then forces are called unbalanced forces.
Example:
⋅ Game of tug of war: When the forces exerted by both the teams are equal, then the rope does not move. But, if the force applied by team A is greater than team B, then the rope, as well as members of the weaker team, i.e., B, will be pulled towards A. The unbalanced force can (a) Set a stationary body in motion.
⋅ Set a moving body at rest.
⋅ Change the direction of motion.
