Here is the problem;
The 40lb block is moving downward with a speed of 3 ft/s at t=0 when constant forces P and 2P are applied through the ropes. Knowing that the block is moving upward with a speed of 2 ft/s when t=4 s, determine (a) the magnitude of P. (b) the time at which the speed is 0 ft/s. Neglect all friction.
**The picture is attached as a pdf, which consists of 4 pulleys.
