A truck is moving 40 m/s when it encounters a ramp inclined by 30% above the horizontal. Gravel provides a frictional force to slow the truck and has a coefficient of friction(.5). How far along the ramp would the truck travel before coming to a stop?

A 50 gram block is placed on a frictionless ramp 2 meters above the ground. It slides down the ramp and compresses a 140 N/m spring at the bottom. How far will the spring be compressed when the block is stopped by the spring? say 1.7 m

The problem propmpts us with the info: "Two friends play with a card-board box on a grassy hill side. The boy in the box has a mass of 50.0 kg and the box has a mass of 5.00 kg. The incline of the hill is 44° and its height is 10 meter. Assume that friction plays a negligible ...
