A 5.0-kg block is pushed 3.0 m up a vertical wall with con- stant speed by a constant force of magnitude Fapplied at an angle of 0 = 30° with the horizontal, as shown in Figure P5.76. If the coef- ficient of kinetic friction between block and wall is 0.30, determine the work done by (a) F, (b) the force of gravity, and (c) the normal force between block and wall. (d) By how much does the gravitational potential energy increase during the block's motion? Figure P5.76
