Potential and Kinetic Energy Answers

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?

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

An object at positionhas about half potential energy and half kinetic energy.

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

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 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?

An object at positionhas all kinetic energy.

An object at positionhas all potential energy.
