1. The m1 = 1.2 kg block at rest on a horizontal frictionless surface is connected to an unstretched spring (k = 130 N/m) whose other end is fixed. (See Fig. 10-36.) The m2 = 2.1 kg block whose speed is 4.0 m/s collides with the 1.2 kg block. Assume that the two blocks stick together after the one-dimensional collision. What maximum compression of the spring occurs when the blocks momentarily stop?
i know the answer is 0.406m, but hav no idea how to get the answer.
