compare the potential energy of a 5 lb ball at the top of a 5 foot hill and a 5 lb ball at the top of a 10 foot hill. question 4 options: their potential energies are the same because they have the same mass. the ball at the top of the 5 foot hill has the least kinetic energy. the ball at the top of the 5 foot hill has the most kinetic energy. kinetic energy doesn't depend on a object's relative height.
