A 2.0 kg block is pushed 2.0 m at a constant velocity up a vertical wall by a constant force applied at an angle of 30.0 ◦ with the horizontal, as shown in the figure. The acceleration of gravity is 9.81 m/s 2 . 2 m 30◦ 2 kg F Drawing not to scale. If the coefficient of kinetic friction between the block and the wall is 0.20, find a) the work done by the force on the block. Answer in units of J. Part 2) the work done by gravity on the block.
Answer in units of J.

Part3) the magnitude of the normal force between
the block and the wall.
