Problem: A 11kg object and a 29 kg object are connected by a massless compressed spring. The two objects and the spring are at rest on a frictionless table. After the spring is released, the objects with the smaller mass has a velocity of 10m/s the the left.
Required:
Question: What is the magnitude of the velocity of the object with the larger mass.
Answer in units of m/s
