Physics

1) A mover pushes a 5.87 kg box with a 48.1 N constanthorizontal force up a 14.9° ramp that has a height of 2.56 m. Ifthe ramp is assumed to be frictionless, find the speed of the boxas it reaches the top of the ramp using work and energy.

2) A 1100 kg car is traveling 35.5 m/s when it comes up to thebottom of a 14.0° hill. If the car coasts up the hill and thecoefficient of rolling friction is 0.450, how far up the hill willthe car travel?
