A luggage handler pulls a 21.0 kilogram suitcase up a ramp inclined at 24.0 degree above the horizontal by a force of magnitude 146 N that acts parallel to the ramp. The coefficient of kinetic friction between the incline and the ramp is µk = 0.300. The suitcase travels 3.20 meter along the ramp.
(a) Find the work done on the suitcase by the force.
J
(b) Find the work done on the suitcase by the gravitational force.
J
(c) Find the work done on the suitcase by the normal force.
J
(d) Find the work done on the suitcase by the friction force.
J
(e) Find the total work done on the suitcase.
J
(f) If the speed of the suitcase is zero at the bottom of the ramp, find its speed after it has traveled 3.20 meter along the ramp?
