A 10 kg box is pulled for 3.60 m along a level surface by a ropethat makes an angle of 37 degrees above the horizontal. The tensionforce in the rope is equal to 85 N. There is a coefficient offriction between the box and the floor of 0.64.
a) Find the work done by each force on the box.
b) Find the net work on the box.
c) If the box starts from rest, what is the speed of the box after traveling 3.6m?
