A ball is rolled at the same starting speed across a smooth floor and then across a rough carpet. The ball travels a shorter distance on the carpet. What is the reason for this?
the carpet destroys the energy in the kinetic store of the ball more quickly
energy is dissipated more quickly by friction between the ball and the carpet
the ball transfers energy from the carpet into its own kinetic energy store
the carpet stores the energy of the ball so that it can be transferred back
