A 4.4-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 0 = 30° with the horizontal, as shown in the figure below. 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 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
