A rocket with a lift-off mass `3.5xx10^4 kg` is blasted upwards with an initial acceleration of `10m//s^2`. Then the initial thrust of the blast is

`3.5xx10^(5) N`

`7.0xx10^(5)N`

`14.0xx10^(5)N`

`1.75xx10^(5)N`

Text Solution

Verified by Experts

The correct Answer is:

Initial thrust of the blast =m(g+a)
`=3.5xx10^(4) xx20`
`=7xx10^(5)N`
