A 5.0 kg block is pushed 3.0 m at a constant velocity up a vertical wall by a
constant force applied at an angle of
30.0° with the horizontal. If the coefficient of kinetic
friction between the block and the wall
is 0.30, determine the following:
a. the work done by the force on the block
b. the work done by gravity on the block
c. the magnitude of the normal force between the
block and the wall
