[#752] Rocket engine

A machine gun fires bullets, each with mass m = 55 \text{ g}m=55 g at a speed of u = 450 \text{ m.s}^{-1}u=450 m.s

. The gun fires 5.05.0 bullets per second. Let's use it as a rocket engine. What thrust does it produce?

Thrust _____ \text{N}N.

Also, list the equations/principles you think might be relevant and I'll comment

Now that's much easier to read. It's always worth checking that the format looks right
