In Fig. 9-64, block 2 (mass 1.0 kg) is at rest on a frictionless surface and touching the end of an unstretched spring of springconstant 200 N/m. The other end of the spring is fixed to a wall.Block 1 (mass 2.0 kg), traveling at speed 4 m/s, collides with block 2, and the twoblocks stick together. When the blocks momentarily stop, by what distance is the spring compressed?
