Potential and Kinetic Energy Answers

If a bouncing ball has a total energy of 20 J and a kinetic energy of 5 J, the ball’s potential energy isJ.

If the kinetic energy of the ball decreases, then the potential energy will.

A roller coaster train with a mass of 500 kg stops at the top of a hill. If the hill is 110 m high, what is the potential energy of the train?

A skier with a potential energy of 137,200 J waits on top of a ski jump that is 200 m high. What is the mass of the skier?

A conveyer belt moves a 40 kg box at a velocity of 2 m/s. What is the kinetic energy of the box while it is on the conveyor belt?
