Review The 5-lb box slides on the surface for which uk = 0.3. The box has a velocity v = 15 ft / s when it is 2 ft from the plate. (Figure 1) %3D Part A If the box strikes the smooth plate, which has a weight of 25 lb and is held in position by an unstretched spring of stiffness k = 400 lb / ft, determine the maximum compression imparted to the spring. Take e = 0.8 between the box and the plate. Assume that the plate slides smoothly. Figure 1 of 1 v = 15 ft/s Express your answer using three significant figures and include the appropriate units. µA 2 ft Value Units
