### 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

Read the passage given below and answer the questions that follow:

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).
