A machine gun fires bullets, each with mass m = 55 , gm=55 g at a speed of u = 450 m.s u=450 m.s
−1
. The gun fires 5.05.0 bullets per second. Let's use it as a rocket engine. What thrust does it produce?
You could have worked it out in the time it's taken you to try to type this twice.
Have you been told/looked up the formula for calculating Thrust?
The N is Newtons in case you weren't sure
