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

Answers

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

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.

Answers

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 object

When 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.

A hole is punched at A in a plastic sheet by applying a 660-N force P to end D of lever CD, which is rigidly attached to the solid cylindrical shaft BC. Design specifications require that the displacement of D should not exceed 15 mm from the time the punch first touches the plastic sheet to the time it actually penetrates it. Determine the required diameter of shaft BC if the shaft is made of a steel with G.

Answers

Answer:

hello your question lacks some data and required diagram

G = 77 GPa,  т all = 80 MPa

answer : required diameter = 252.65 * 10-^3 m

Explanation:

Given data :

force ( P )  = 660 -N force

displacement = 15 mm

G = 77 GPa

т all = 80 MPa

i) Determine the required diameter of shaft BC

considering the vertical displacement ( looking at handle DC from free body diagram )

D' = 0.3 sin∅  ,   where D = 0.015

hence ∅ = 2.8659°

calculate the torque acting at angle ∅  of  CD on the shaft BC

Torque = 660 * 0.3 cos∅

             = 660 * 0.3 * cos 2.8659 = 198 * -0.9622 = 190.5156 N

hello attached is the remaining part of the solution

The required diameter of shaft BC will be 252.65 ×10⁻³A shaft's diameter is the line that goes through its center and splits it into two equal halves.

What is the diameter?

A diameter is a line that travels through the center of a sphere and intersects the circumference at opposing ends. It measures twice as long as the sphere's radius

The given data in the problem is;

P is the force = 660 N

d is the displacement = 15 mm

G is the constant= 77 GPa

τ is the shear stress= 80 MPa

From the torsional equation;

[tex]\frac{\tau}{R} =\frac{T}{j} \\\\ \frac{\pi}{32} \times d^4=\\\\ \tau =\frac{T \times R}{J} \\\\\ \tau =\frac{T \times (\frac{d}{2} )}{J} \\\\ 80= \frac{32 \times 190 \times \frac{d}{2} }{\pi} \\\\\\d=252.65 \times 10^{-3}[/tex]

Hence the required diameter of shaft BC will be 252.65 ×10⁻³.

A cartoon shows two friends watching an unoccupied car in free fall after it has rolled off a diff. One friend says to the other, "It goes from zero to sixty mphin about three seconds." Is this statement correct? (Note that 60 mph converts to 26.8 m/s.)

Answers

Answer:

The statement is not correct.

Explanation:

To know if the statement is correct, we shall determine the velocity of the car after 3 s. This is illustrated below.

Data obtained from the question include:

Initial velocity (u) = 0 m/s

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) = 3 s

Final velocity (v) =?

v = u + gt

v = 0 + (9.8 × 3)

v = 0 + 29.4

v = 29.4 m/s

Thus, the velocity of the car after 3 s is 29.4 m/s.

Hence, the statement made by the friend is not correct as the car has a falling velocity of 29.4 m/s after 3 s.

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

Answers

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]

If a 40 kg pumpkin is thrown through your neighbors window with an acceleration rate of 2 m/s, what’s the force you through it with?

Answers

Answer:

[tex]\boxed {\boxed {\sf 80 \ Newtons}}[/tex]

Explanation:

Force can be found by multiplying the mass by the acceleration.

[tex]F=m*a[/tex]

The mass of the pumpkin is 40 kilograms.

The acceleration of the pumpkin is 2 meters per second squared.

[tex]m= 40 \ kg \\a= 2 \ m/s^2[/tex]

Substitute the values into the formula.

[tex]F= 40 \ kg *2 \ m/s^2[/tex]

Multiply.

[tex]F= 80 \ kg*m/s^2[/tex]

A kilogram meter per second squared is equal to 1 Newton. Therefore, our answer of 80 kg*m/s² is also equal to 80 Newtons (N).

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

Answers

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 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?

Answers

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.
