A mass, m1 = 7.98kg is at rest on a frictionless horizontal surface and connected to a wall by a spring with k= 64.6 N/m. A second mass, m2 =4.94kg, is moving to the right at v0= 26.2 m/s. The two masses collide and stick together.
a) What is the maximum compression of the spring?
b) How long will it take after the collision to reach this maximum compression?
