A 5-kg block is pushed 3 m up a vertical wall with constant speed by a constant force of magnitude f applied at an angle of 30 degrees with the horizontal. If the coefficient of kinetic friction between the block and the wall is 0.3, determine the work done by
a) f
b) the force of gravity
c) the normal force between block and wall
d) By how much does the gravitational potential energy increase during the block's motion?
