1. A 50.0 kg block is pulled from rest by a force of 1000.0 N at an angle of 37.0° across a horizontal rough surface over a
distance of 5.60 m. The coefficient of kinetic friction between the block and the surface is 0.500.
a) Draw a free body diagram and show all the applied forces.
b) How much work is done by force F?
c) How much work is done by the normal force?
d) How much work is done by the gravitational force?
e) How much work is done by the friction force?
f) What is the net work done on the block?
g) What is the change in kinetic energy of the block?
