A mass (m1 = 3.0 kg) with initial velocity V0 = 2.0 m/s strikes a mass-spring system (m2 = 1.0 kg) initially at rest but able to recoil. The spring is massless with spring constant k = 7.5 N/m. There is no friction.
A) Is momentum conserved in this collision? Explain.
B) What is the maximum compression of the spring?
