Problem 6.76
For the position shown in the figure the spring is unstretched. The spring constant k, is designed such that after the system is released from rest, the speed of the mass is zero just as the 0.6 slug mass touches the floor. Find the spring constant, k and the maximum speed of block A and the location (distance above floor) where this occurs.
