Question: a. Starting from rest, a crate of mass m is pushed up a frictionless slope of angle by a horizontal force of magnitude F.
a. Starting from rest, a crate of mass m is pushed up a frictionless slope of angle θ by a horizontal force of magnitude F. Use work and energy to find an expression for the crate’s speed v when it is at height h above the bottom of the slope.
b. Doug uses a 25 N horizontal force to push a 5.0 kg crate up a 2.0-m-high, 20° frictionless slope. What is the speed of the crate at the top of the slope?
