A shell of mass 10 kg is moving with a velocity with a velocity of `10ms^(-1)` when it blasts and forms two parts of mass 9 kg and 1 kg respectively. If the 1st mass is stationary, the velocity of the 2nd is

A

1 m/s

B

10 m/s

C

100 m/s

D

1000 m/s

Verified by Experts

The correct Answer is:

C

`Mv = m_(1)mv_(1) + m_(1)v_(2)`
`rArr 10 xx 10 = 9 xx 0 + 1 xx v_(2) rArr v_(2) = 100 m//s`
