Starting from rest, a crate of mass is pushed up a frictionless slope of angle by a horizontal force of magnitude.
PART A: Use work and energy to find an expression for the crate's speed when it is at height above the bottom of the slope. Express your answer in terms of the variables m,F , theta , h, and free fall acceleration g.
PART B: Doug uses a 29 horizontal force to push a 3.5 crate up a 1.5 -high, 20 frictionless slope. What is the speed of the crate at the top of the slope? Express your answer to two significant figures and include the appropriate units.
