1. A cart with a mass of 3.00 kg rolls from the top of an inclined
that is 7.50 m long with its upper end at a height of 3.75 m above
the ground. The force of friction acting on the cart as it rolls is
4.50 N in magnitude. (a) What is the change in gravitational
potential energy when the cart moves from the top of the inclined
plane to ground level? (b) What is the work done by friction?
