Show work

49. | | Two blocks with masses MA and my are connected by a massless string over a massless, frictionless pulley. Block B, which is more massive than block A, is released from height h and falls. a. Write an expression for the speed of the blocks just as block B reaches the ground. b. A 1.0 kg block and a 2.0 kg block are connected by a massless string over a massless, frictionless pulley. The impact speed of the heavier block, after falling, is 1.8 m/s. From how high did it fall
