A rocket with a lift - off mass 20,000 ...

A rocket with a lift - off mass 20,000 kg is blasted upwards with an initial acceleration of `50 ms^(-2)`. Calculate the initial thrust (Force ) of the blast .

Text Solution

Verified by Experts

Given
Initial mass of the rocket , m= 20,000 kg
Initial acceleration `a=50 ms^(-2)`
(Upward direction )
Let initial thrust of the blast be T
To find : T=mg+ma
Solution
`T=m(g+a)=20,000 (9.8+50)`
`T=2xx10^(4) xx 59.8`
Initial thrust , `T=119.6xx10^(4)N`
