A luggage handler pulls a suitcase of mass 28.3 kg up a ramp inclined at an angle 20.8 degrees above the horizontal by a force (F) of magnitude 265 N that acts parallel to the ramp. The coefficient of kinetic friction between the ramp and the incline is 0.255. The suitcase travels a distance 3.01 meters along the ramp. Work done on the suitcase is 798 Joules, work done on the suitcase by gravitational force is -296 Joules, and the Work done on the suitcase by the normal force is 0 Joules. Calculate the work done on the suitcase by the friction force. Calculate the total work done on the suitcase.
