Question

A 1.0-kg block (Block 1) at rest on a horizontal frictionless surface is connected to unstretched spring Ck 400 N/m) whose other end is fixed. A 2.0-kg block (Block 2) moving at 4.0 m/s collides with Block 1. Block 2 is found to move leftward with a speed of 1 m/s after collision. (1) What is the speed of Block 1 after collision? (6 pts) (2) What maximum compression of the spring occurs when Block I momentarily stops? (6 pts) 4.0 m/s o s
