Starting from rest, a crate of mass m is pushed up a frictionless slope of angle by a *horizontal* force of magnitude . Use work and energy to find an expression for the crates speed when it is at height above the bottom of the slope.

Doug uses a 28 N horizontal force to push a 4.1 kg crate up a 1.8 m -high, 20^{} frictionless slope. What is the speed of the crate at the top of the slope?
