A 3.8-kg block is pushed 3.5 m up a vertical wall with constant speed by a constant force of magnitude F applied at an angle of θ = 30 with the horizontal. If the coefficient of kinetic friction between block and wall is 0.30, determine the following. 
(a) the work done by F
 J

(b) the work done by the force of gravity
  J

(c) the work done by the normal force between block and wall
  J

(d) By how much does the gravitational potential energy increase during the block’s motion?
  J
