Concept

Problem: Starting from rest, a crate of mass m is pushed up a frictionless slope of angle heta by a horizontal force of magnitude F. Use work and energy to find an expression for the crates speed v when it is at height h 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?
