The spring bumper is used to
arrest the motion of the 8 lb block, which is sliding toward it at
5 ft/s . As shown, the spring is confined by the plate P and wall
using cables so that its length is 1.5 ft.
(Figure 1)
Part A
If the stiffness of the spring is k = 50 lb/ft, determine the
required unstretched length of the spring so that the plate is not
displaced more than 0.2 ft after the block collides into it.
Neglect friction, the mass of the plate and spring, and the energy
loss between the plate and block during the collision.
Express your answer to three significant figures and include the
appropriate units.

The 52-lb block rests on the rough surface for which the coefficient of kinetic friction is mu_k = 0.2. A force F = (40 + s^2) lb, where s is in ft, acts on the block in the direction shown. The spring is originally unstretched (s = 0) and the block is at rest. (Figure 1) Part A Determine the power developed by the force the instant the block has moved s = 1.5 ft.
