A bumper, consisting of a nest of three springs, is used to arrest the horizontal motion of a large mass which is traveling at 33 m/s as it contacts the bumper. The two outer springs cause a deceleration proportional to the spring deformation. The center spring increases the deceleration rate when the compression exceeds 0.8 m as shown on the graph. Determine the maximum compression xof the outer springs. Deceleration m/s? 3060 2040 1020 x, m 0.8 1.6 33 m/s Answer:x-

During braking, a truck has a steady deceleration of 7.0 m/s². A box sits on the platform of this truck. The box begins to slide when the braking begins and, after sliding a distance of 2.0 m (relative to the truck), it hits the front of the truck. With what speed (relative to the truck) does the box hit? The coefficient of kinetic friction for the box is μk=0.50.

Two weights of 96 pounds and 64 pounds move horizontally on a surface smooth, each spring has k = k1 = k2 = 600. At t = 0 the springs are unstretched and the weight of 96 has a velocity of 600 ft/sec away from the wall and the other is in repose. Solve the system of equations for the given conditions, and explain how the equations of motion are obtained for each mass ('x(t)' and 'y(t)').
