A luggage handler pulls a 20.O-kg suitcase up a ramp inclined at 25.0° above the horizontal by a force F of magnitude 140 N that acts parallel to the ramp. The coefficient of kinetic friction between the ramp and the incline is μk = 0.300. If the suitcase travels 3.80 m along the ramp, calculate
(a) The work done on the suitcase by the force F;
(b) The work done on the suitcase by the gravitational force;
(c) The work done on the suitcase by the normal 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 suitcase is zero at the bottom of the ramp, what is its speed after it has traveled 3.80 m along the ramp?
