A girl on a bicycle has a specific amount of kinetic energy at the base of a hill. She then coasts up the hill without pedaling. She

comes to a stop at the top of the hill. Why is her potential energy at the top of the hill less than her kinetic energy at the bottom of
the hill?
les )
The hill did work on the bicycle as she went up the hill.
The rest of the energy is stored in the muscles of her body.
She still has kinetic energy while stopped on top of the hill
Friction and air resistance created heat on her trip up the hill
