Gravitational Potential Energy and Kinetic Energy
 

Gravitational Potential Energy and Kinetic Energy problem 30


A tennis ball weighs 56 g. It is dropped from a height of 1.25 m so that it falls freely. Air resistance can be ignored.

  • Calculate the potential energy the ball has before releasing it.

  • At what speed does the ball hit the ground?

  • How long does it take for the ball to fall?
