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
(b) the work done by the force of gravity
(c) the work done by the normal force between block and wall
(d) By how much does the gravitational potential energy increase during the block's motion?
