A 2.00-kg block slides down a board 1.50 mlong which is inclined at an angle of 40.0°.
The coefficient of friction between the block and the board is 0.200.
i. Find the work done by each force that acts on the blockas it slides from the top to the bottom of the board.
ii. If the block was released from rest at the top of the board, what is its speed when it reaches the bottom of the board?
