Homework Statement
In the figure below, block 1 (mass 1.6 kg) is moving rightward at 8 m/s and block 2 (mass 4.2 kg) is moving rightward at 2.8 m/s. The surface is frictionless, and a spring with spring constant of 1120 N/m is fixed to block 2. When the blocks collide, the compression of the spring is maximum at the instant the blocks have the same velocity. Find the maximum compression.
