(a) How much work is done by the horizontal force F_p = 150 N on the 18 kg block of the figure when the force pushes the block 5.5 m up along the 32 degree frictionless incline?
(b) How much work is done by the gravitational force on the block during this displacement?
(c) How much work is done by the normal force?
(d) What is the speed of the block (assume that it's zero initally) after this displacement?
