Question
A ball of mass m = 60gm is shot with speed v0 = 22m/s into the barrel of spring gun of mass M = 240g initially at rest on a frictionless surface. The ball sticks in the barrel at the point of maximum compression of the spring.
The speed of the spring gun after the ball stops relative to the barrel, is
- 2.2 m/s
- 4.4 m/s
- 4.4 cm/s
- none
The correct answer is: 2.2 m/s

A buggy of mass 100 kg is free to move on a frictionless horizontal track. Two men, each of mass 50 kg, are standing on the buggy, which is initially stationary. The men jump off the buggy with velocity=10m/s relative to the buggy. In one situation, the men jump one after the other. In another situation, the men jump simultaneously. What is the ratio of the recoil velocities of the buggy in two cases?
