In the figure, block 2 is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant ?. The other end of the spring is fixed to the wall. Block 1, traveling with a speed ?0, collides with block 2, and the two blocks undergo an elastic collision. When the block 2 momentarily stops, by what distance is the spring compressed? Your result should be a function of the masses of each block, the speed of block 1, and the spring constant.
