Just for fun, two 150-lb engineering students A and B intend to jump off the bridge from rest using an elastic cord having a stiffness k=80lb/ft. They wish to just reach the surface of the river, when A, attached to the cord, lets go of B at the instant they touch the water. Determine the proper unstretched length of the cord to do the stunt, and calculate the maximum acceleration of students A and maximum height he reaches above the water after the rebound. From your results, comment on the feasibility of doing the stunt.
