14-34. The spring bumper is used to arrest the motion of the 4-lb block, which is sliding toward it at v = 9 ft/s. As shown, the spring is confincd by the plate P and wall using cables so that its length is 1.5 ft. 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. -1.5 ft ft

Determine the maximum compression of the spring after the collision.
The smooth particle has a mass of 80g. It is attached to an elastic cord extending from O to P and due to the slotted arm guide moves along the horizonta! circular path r = (0.8 sin 8)m. If the cord has a stiffness k = 30(N/m) and an un-stretched length of 0.25m, determine the angular velocity required so the force of the guide on the particle is 7.67N when 0 = 60°. 0.4 m
