A luggage handler pulls a suitcase of mass 16.6kg up a ramp inclined at an angle 20.0 above the horizontal by a force of magnitude 149N that acts parallel to the ramp. The coefficient of kinetic friction between the ramp and the incline is 0.262. The suitcase travels a distance 3.70m along the ramp.
Calculate the work done on the suitcase by the force F.
I am doing
W= 149*cos(20)*3.7
=518
and its not correct
