Question

A solid block of mass m2 = 8.3 kg, at rest on a horizontal frictionless surface, is connected to a relaxed spring. The other end of the spring is fixed, and the spring constant is k = 210 N/m. Another solid block of mass m1 = 12.4 kg and speed v1 = 4.9 m/s collides with the 8.3 kg block. The blocks stick together, and compress the spring. What is the maximum compression of the spring? What is the magnitude of the acceleration of the two blocks when the spring is at maximum compression?
