Consider a hanging spring of negligible mass that does not obey Hooke's law. When the spring is pulled downward by a distance x, the spring exerts an upward force of magnitude ar, where a is a positive constant. Initially the hanging spring is relaxed (not extended). We then attach a block of mass m to the spring and release the block. The block stretches the spring as it falls (see figure). (a) How fast is the block moving when it has fallen a distance x,? (b) At what rate does the spring do work on the block at this point? (c) Find the maximum distance x2 that the spring stretches. (d) Will the block remain at the point found in part ©?

An inclined plane of angle e = 20.0° has a spring of force constant k = 510 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure below. A block of mass m = 2.61 kg is placed on the plane at a distance d = 0.297 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?
