Two blocks are connected by a light string that passes over two frictionless pulleys as in Figure P5.24. The block of mass m2 is attached to a spring of force constant k and m1 m2. If the system is released from rest, and the spring is initially not stretched or compressed, find an expression for the maximum displacement d of m2. Figure P5.24

Starting from rest, a 64.0 kg woman jumps down to the floor from a height of 0.610 m, and immediately jumps back up into the air. While she is in contact with the ground during the time interval 0 < t < 0.800 s, the force she exerts on the floor can be modeled using the function F = 9,200t − 11,500t2 where F is in newtons and t is in seconds. c) With what speed (in m/s) did she leave it? (Round your answer to at least three significant figures.) d) To what height (in m) did she jump upon leaving the floor?
