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

A rocket with a lift-off mass 20,000 kg is blasted upwards with an initial acceleration of `5.0 m s^-2`. Calculate the initial thrust (force) of the blast.

Text Solution

Verified by Experts

We are given:
`M= 2 xx 10^(4) kg` and `(Deltav)/(Deltat)= 5 ms^(-2)`
We know that, net force= upthrust - weight of the rocket
Upthrust= net force + weight =`Ma+ Mg= M(a+g)`
`= 2 xx 10^(4)(5+9.8)= 2.96 xx 10^(5) N`
