An 8.5-kg block is pushed along a horizontal rough surface by a 40-N force inclined at 20° with the horizontal. The coefficient of friction between the surface and block is 0.35. If the block has an initial velocity of 3.6 m/s and the force does 200 J of work on the block, find: (a) The total distance moved by the block. (b) The final velocity of the block.

Question
An 8.5-kg block is pushed along a horizontal rough surface by a 40-N force inclined at
20° with the horizontal. The coefficient of friction between the surface and block is
0.35. If the block has an initial velocity of 3.6 m/s and the force does 200 J of work on
the block, find:
(a) The total distance moved by the block.
(b) The final velocity of the block.
