Determine the speed of block A after it moves a distance d down the plane, starting from rest. Neglect friction and the mass of the cord and pulleys. Given: W A 60 lb = e 3 = W B 10 lb = f 4 = d 5f t = g 32.2 ft s 2 = Solution: L 2 s A s B + = 02 Δ s A s B + = v A v B + = T 1 0 = V 1 0 = T 2 1 2 W A g v A 2 1 2 W B g v B 2 + = V 2 W A
