The 7-1b box slides on the surface for which μ = 0.3. The box has a velocity v = 15 ft/s when it is 2 ft from the plate. (Figure 1) Figure 2 = 15 ft/s 2 ft < 1 of 1 > Pr
Part A If the box strikes the smooth plate, which has a weight of 21 lb and is held in position by an unstretched spring of stiffness k = 290 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.
