A block of mass M is dropped from a height H onto a vertical spring as shown in Figure A. The spring elastic constant is k. The block sticks to the spring and the spring compresses by L before coming momentarily to rest. a) How much work is done by the force of gravity while the spring is being compressed? b) How much work is done by the spring? c) What was the speed of the block just before it hit the spring?
