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.
(c) Calculate the work done on the suitcase by the normal force.
(d) Calculate the work done on the suitcase by the friction force.
(e) Calculate 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 3.00 m along the ramp?
m/s
