A rocket of mass 120kg. Is fired in the gravity free space is ejected gases with velocity 600 m/s at the rate of 1kg/s. what will be the initial accleration of the rocket:-

A

`1m//s^(2)`

B

`5m//s^(2)`

C

`10m//s^(2)`

D

`15m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B

`F=1xx600`
`therefore a=(600)/(120)=5 m//s^(2)`
