              Question:
              A 2.65 block is pushed 1.69m up a vertical wall with a constant speed by a constant force of
              magnitude F applied at angle 55.4 degrees with the horizontal. g= 9.8 m/s2. If the coefficient of
              kinetic friction between the block and wall is 0.54, find the work done by the F and express in J.
