A luggage handler pulls a 20.0-kg suitcase up a ramp inclined at 24.0° above the horizontal by a force of magnitude 148 N that acts parallel to the ramp. The coefficient of kinetic friction between the ramp and the incline is µk = 0.300. The suitcase travels 3.00 m along the ramp.
(a) Calculate the work done on the suitcase by the force .
J
(b) Calculate the work done on the suitcase by the gravitational force.
J
(c) Calculate the work done on the suitcase by the normal force.
J
(d) Calculate the work done on the suitcase by the friction force.
J
(e) Calculate the total work done on the suitcase.
J
(f) If the speed of the suitcase is zero at the bottom of the ramp, what is its speed after it has traveled 3.00 m along the ramp?
