A ball is thrown straight up. At what point does the ball have the most energy? Ignore air resistance.

A bowling ball is dropped from a height h onto the center of a trampoline, which launches the ball back up into the air. How high will the ball rise?

A car traveling at a velocity v can stop in a minimum distance d. What would be the car's minimum stopping distance if it were traveling at a velocity of 2v?

When the speed of your car is doubled, by what factor does its kinetic energy increase?

A satellite in circular orbit around the Earth moves at con stant speed. This orbit is maintained by the force of gravity between the Earth and the satellite, yet no work is done on the satellite. How is this possible?

You push very hard on a heavy desk, trying to move it. You do work on the desk:

A 66-kg skier starts from rest at the top of a 1200-m- long trail which drops a total of 230 m from top to bottom. At the bottom, the skier is moving 11.0 m/s. How much energy was dissipated by friction? (Give your answer to two significant figures)

You drop a ball from a height of 2.0 m, and it bounces back to a height of 1.6 m. What fraction of its initial energy is lost during the bounce? (Give your answer as a percentage)

A 145-g baseball is dropped from a tree 12.0 m above. If it hits the ground with a speed of 8.00 m/s, what is the average force of air resistance exerted on it?

A 16.0-kg child descends a slide 2.20 m high and, starting from rest, reaches the bottom with a speed of 1.25 m/s. How much thermal energy due to friction was generated in this process?
