A daredevil on a motorcyclo attempts to clear a 420-meter-wide river from a 210-meter-high cliff. What must his initial horizontal velocity
be?
Answer:
His initial velocity (speed) must be 64.16 m/s.
Explanation:
Horizontal Motion
When an object is horizontally launched at a speed v from a height h, the maximum horizontal distance (also called Range) traveled by the object can be calculated as follows:
[tex]\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}[/tex]
Our daredevil is attempting to clear a river d=420 m wide with his motorcycle from a cliff h=210 m high. We need to find the speed needed to safely reach the opposite edge of the river.
From the above equation, we solve for v:
Speed:
[tex]\displaystyle v=d\cdot\sqrt{\frac {g}{2h}}[/tex]
[tex]\displaystyle v=420\cdot\sqrt{\frac {9.8}{2\cdot 210}}[/tex]
[tex]\displaystyle v=420\cdot\sqrt{\frac {9.8}{420}}[/tex]
v = 64.16 m/s
His initial velocity (speed) must be 64.16 m/s.
A paper airplane moves at a constant velocity of 10 m/s to the east when there is no wind of 19 m/s begins to blow?
Answer: So if the steady easterly wind of 19 m/s begins to blow more than the 10 m/s it just needs more wind and direction So the resultant has to be 29 m/s east.

You accelerate from 2m/s to 6m/s while traveling a distance of 2m; what was your acceleration?
A.4 m/s^2
B.8 m/s^2
C.12 m/s^2
D.16 m/s^2
Answer:
The acceleration is 8 m/s²
Explanation:
The given parameters are;
The initial velocity, u = 2 m/s
The final velocity, v = 6 m/s
The distance the acceleration took place, s = 2 m
The acceleration, a, can be found from the following kinematic equation;
v² = u² + 2·a·s
By substituting the values, we have;
6² = 2² + 2 × a × 2
6² - 2² = 2 × a × 2
32 = 4·a
a = 32/4 = 8 m/s²
The acceleration, a, of the given motion = 8 m/s².
Ejercicio 1: Un cuerpo gira en un círculo de 8cm de diámetro con una rapidez constante
de 7km/h. ¿Cuál es la aceleración centrípeta expresada en m/s? Recordar que el radio es
la mitad del diámetro.
Ejercicio 2: Las cargas están interactuando en un medio desconocido con una fuerza de
-5N con una separación de 40cm teniendo sus respectivas cargas de 3.5 milicoulombs y
6 milicoulombs.
Answer:
Exercise 1;
The centripetal acceleration is approximately 94.52 m/s²
Explanation:
1) The given parameters are;
The diameter of the circle = 8 cm = 0.08 m
The radius of the circle = Diameter/2 = 0.08/2 = 0.04 m
The speed of motion = 7 km/h = 1.944444 m/s
The centripetal acceleration = v²/r = 1.944444²/0.04 ≈ 94.52 m/s²
The centripetal acceleration ≈ 94.52 m/s²

Which of the following provides evidence that there must be at least two types of electrical charge, but that there is only one type of mass?
A.) The magnitude of the Coulomb's law constant differs greatly from the magnitude of the universal gravitational constant.
B.) Contact forces such as friction are caused primarily by electrostatic forces and not by gravitational ones.
C.) The electric force has a relative strength that is much greater than the strength of the gravitational force.
D.)On the scale of the solar system, electric forces cancel out and gravitational forces dominate.
Answer:
Option D (On the...............dominate) would be the right approach.
Explanation:
The Gravitational constant (G) will be:
= [tex]6.67\times 10^{-11}[/tex]
The Coulomb's law constant (K) will be:
= [tex]9\times 10^9[/tex]
Throughout particular, these have been determined that among 2 substances with almost the similar form of charge, the combination of electromagnetic as well as the force does seem to be usually the following:⇒ [tex]\frac{f_e}{f_g}\sim 10^{42}[/tex]

It is quite since there are so many categories of allegations throughout the planet's atmosphere that balance out someone else's effects, there's only yet another form of momentum, because although the forces are still cumulative, as well as therefore offering to help everything hold to the universe, encouraging the universe just to rotate across the sun.The latter three choices aren't connected to either the situation mentioned in the clarification segment elsewhere here.
The statement that provides evidence that there must be at least two types of electrical charge, but that there is only one type of mass is that on the scale of the solar system, electric forces cancel out and gravitational forces dominate.
The examples that provides conclusive evidence of is option d because the Gravitational constant is (G)=6.67*10-11 while the Coulomb's law constant(K)=9*109.
Coulomb's law often connotes that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.The interaction between charged objects is regarded as a non-contact force that acts over some distance of separation.

Compare and contrast mechanical energy of a projectile with mechanical energy of a swing
Answer:
mechanical energy is due to the position and the motion of an object in a system. A projectile moves in a curve. When the object leaves, it has mostly kinetic energy
Explanation:
On a swing, the ride starts with a push, giving you kinetic energy.
When the pendulum swings, its potential energy transforms into kinetic energy.While projectile energy transforms from kinetic energy to potential energy.
What is the difference between projectile and swing?
Swinging from a pendulum, such as a rope swing or a hanging vine, is more difficult than swinging from a cannonball projectile.
A type of motion in which an item moves along a bilaterally symmetrical, parabolic direction is known as projectile motion.
The path that the item takes is referred to as its trajectory. Projectile motion occurs only when a single force is supplied at the start of the trajectory, after which the only interference comes from gravity.
Because gravity is the sole force acting on a projectile while it is in the air, the total energy does not vary at any point in its travel,
The energy can change forms from kinetic energy, The energy of motion, to potential energy, or from potential energy to kinetic energy.
When the pendulum swings, its potential energy transforms into kinetic energy, which is then converted back to potential energy, which is then converted back to kinetic energy, and so on.
Let's try it with a tire swing as a pendulum to see how it works! All of the swing's mechanical energy is potential energy at its beginning location.
Hence when the pendulum swings, its potential energy transforms into kinetic energy. While projectile energy transforms from kinetic energy to potential energy.

Is friction an unbalanced force yes or no?
Answer: (Remember: a force is not needed to keep a moving object moving to the right.) ... Yet there is no force present to balance the force of friction. As the book moves to the right, friction acts to the left to slow the book down. There is an unbalanced force; and as such, the book changes its state of motion.
Explanation:
When the forces acting on an object are unbalanced, they do not cancel out one another. An unbalanced force acting on an object results in the object's motion changing. ... Friction is a force that resists the motion or the tendency toward motion between two objects in contact with each other.

A)The gravitational potential energy is the same for all of the hikers.
B)The hiker who took Path 1
C)The hiker who took Path 2
D)The hiker who took Path 3
Answer: a
Explanation:
cause i took a test and that is what my science teacher said
Option A - The gravitational potential energy is the same for all of the hikers is correct.
We have three hikers who took three different paths to the top of a mountain labelled as paths 1, 2, and 3. The hikers are all the same height and weight.
We have to find which hiker will have the greatest amount of gravitational potential energy at the top.
What is the gravitational potential energy of the body of mass ' m ' at a height ' h ' above the surface of earth (h <<R)?The formula to calculate the gravitational potential energy is -
U (h) = mgh
In the question given to us -
Mass of each hiker is same = m kg
Height of each hiker at top is same = h meters
The gravitational Potential Energy of a body is independent of the path taken. Since the mass and height of each hiker is same, therefore -
U (h[1]) = U(h[2]) = U(h[3]) = mgh
Hence, Option A is correct.

Explanation:
For a projectile with no air resistance, at the peak of its path, _______________.
Answer: "For a projectile with no air resistance, at the peak of its path, it's velocity is equal to zero"
Explanation:
Suppose that you throw an object up. The initial vertical velocity will be positive, and the acceleration (the gravitational acceleration) will point downwards, meaning that it opposes to the initial direction of the velocity, and that decreases the velocity as the time goes by.
There will be a point where the velocity ( that was positive until now, so until now the height of the object was increasing), is equal to zero, this means that at this moment the object stops moving, and after, because we still have negative acceleration, the velocity will start become negative, and the object will fall down.
Then that point where the velocity was zero is the peak of its path, then we can conclude that:
"For a projectile with no air resistance, at the peak of its path, it's velocity is equal to zero"
