The spring has a stiffness k = 50 lb/ft and an unstretched length of 2 ft. As shown, it is confined by the plate and wall using cables so that its length is 1.5 ft. A 5-lb block is given a speed A when it is at A, and it slides down the incline having a coefficient of kinetic friction µ = 0.2. It strikes the plate and pushes it forward 0.25 ft before stopping. Neglect the mass of the plate and spring. (Figure 1), Figure k = 50 lb/ft 1.5 ft 3 ft
