The 40-lb block starts from rest and moves upward when constant forces of 10 lb and 20

Question:

The 40-lb block starts from rest and moves upward when constant forces of 10 lb and 20 lb are applied to supporting ropes. Neglecting the masses of the pulleys and the effect of friction, determine the speed of the block after it has moved 1.5ft.
