The man A has a weight of 175 lb and jumps from rest h = 8 ft onto a platform P that has a weight of 60 lb. The platform is mounted on a spring, which has a stiffness k = 200 lb/ft. Determine
(a) The velocities of A and P just after impact and
(b) The maximum compression imparted to the spring by the impact. Assume the coefficient of restitution between the man and the platform is e = 0.6. And, and the man holds himself rigid during the motion. |
