The force-compression profile of a rubber bumper B is given by FB = Bx, where
B = 3.5 x 10 lb/ft and x is the bumper's compression measured in the horizontal
direction. Determine the expression for the potential energy of the bumper B. In addition,
if the cruiser C weighs 70,00O lb and impacts B with a speed of 5 ft/s, determine the
compression required to bring C to a stop. Model C as a particle and neglect C's vertical
motion as well as the drag force between the water and the cruiser C.
