### Question

rifle man, who together with his rifle has a mass of 100 kg, stands on a smooth surface fires 10 shots horizontally. Each bullet has a mass 10 gm and a muzzle velocity of 900 m/s. What velocity does rifle man acquire at the end of 10 shots.

### Choices

Choice (4) Response

a.

0.3 m/s

b.

0.6 m/s

c.

0.9 m/s

d.

0.5 m/s

## Passage

A small particle of mass m/10 is moving horizontally at a height of 3R/2 from ground with velocity 10 m/s. A perfectly inelastic collision occurs at point P of sphere of mass m placed on smooth horizontal surface. The radius of sphere is R, (m = 10 kg and R = 0.1 m) (Assume all surfaces to be smooth).
