    You push a crate of mass 27 kg 15 m up a ramp that is sloped 19° above the horizontal. The coefficient of kinetic friction between the ramp and the crate is 0.15, and the speed of the crate, which starts from rest, is 1.7 m/s at the end of the 15 m. To accomplish the task, you apply a variable force directed along the ramp. (a) Calculate the change in the crate’s gravitational potential energy (crate–Earth system). (b) Calculate...
