A crate with a mass of in is on a ramp that is inclined at an angle of 30o from the horizontal. A force with a magnitude of F directed parallel to the ramp is used to pull the crate with a constant speed up the ramp a distance of d.
1. What is the work done on the crate by the frictional force F?
2. What is the work done on the crate by the total force?
3. What is the total force acting on the crate?
