A luggage handler pulls a 20.0 kg suitcase up a ramp inclined at 33.0° above the horizontal by a force of magnitude 167 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 3.70 m along the ramp. Calculate the work done on the suitcase by the handler's force.
a) 469.71 J
b) 509.05 J
c) 534.21 J
d) 575.08 J
