Question

A uggage andler pulls g suitcase up a ramp in-clined at 32.0* above the horizontal by a force F of magnitude 160 N that acts parallel to the ramp. The coefficient of kinetic friction between the ramp and the incline is 14 = 0.300. If the suitcase travels 3.80 m along the ramp, calculate (a) the work done on the suitcase by F.; (b) the work done on the suitcase by the gravitational force; (c) the work done on the suitcase by the nor-mal force; (d) the work done on the suitcase by the friction force; (e) the total work done on the suitcase. (f) If the speed of the suit-case is zero at the bottom of the ramp, what is its speed after it has traveled 3.80 m along the ramp?
