## Homework Statement

A 20,000 kg rocket exhausts gasses at a constant 700 kg/sec at 300 ms^-1

Deduce the thrust applied to the rocket by its engines

## Homework Equations

The only equation I know is a= T- mg/m

Where T= thrust

a=acceleration

m=mass

## The Attempt at a Solution

I don't know any other formulas and I can't use the one above because I don't have the acceleration

Please help??
