A stone is thrown downwards from the edge of a cliff with a speed of 5.0 m s–1. It hits the ground 2.0 s later. What is the height of the cliff?
- An object of mass m is sliding down a ramp at constant speed. During the motion it travels a distance 𝑥 along the ramp and falls through a vertical distance h. The coefficient of dynamic friction between the ramp and the object is μ. What is the total energy transferred into thermal energy when the object travels distance 𝑥?
- Two blocks of masses m and 2m are travelling directly towards each other. Both are moving at the same constant speed v. The blocks collide and stick together. What is the total momentum of the system before and after the collision?
- The graph shows the variation with time of the resultant net force acting on an object. The object has a mass of 1kg and is initially at rest. What is the velocity of the object at a time of 200 ms?
- An object has a weight of 6.10 × 102 N. What is the change in gravitational potential energy of the object when it moves through 8.0 m vertically?
- A boat with an output engine power of 15 kW moves through water at a speed of 10 m s-1. What is the resistive force acting on the boat?
- The graph shows the variation of momentum with time for an object.What net force acts on the object for the first 2.0 s and for the second 2.0 s of the motion?
-A truck has an initial speed of 20 m s–1. It decelerates at 4.0 m s
–2. What is the distance taken by the truck to stop?
- A ball of mass m collides with a wall and bounces back in a straight line. The ball loses 75 % of the initial energy during the collision. The speed before the collision is v. What is the magnitude of the impulse on the ball by the wall.
- An object falls from rest from a height h close to the surface of the Moon. The Moon has no atmosphere. When the object has fallen to height ℎ/4
above the surface, what is kinetic energy of the object at ℎ/
4/gravitational potential energy of the object at ℎ?
