A machine gun has a mass 5 kg. It fires 50 gram bullets at the rate of 30 bullets per minute at a speed of 400 m/s. What force is required to keep the machine gun in position?

Solution

Mass of the gun = 5 kg
Mass of bullets =50 g
Speed at which the bullet is fired = 400 m/s
Therefore, force required to keep the machine gun in position =

fraction numerator Change space in space momentum space of space bullets over denominator time space taken end fraction

equals space fraction numerator left parenthesis 50 space straight x space 10 to the power of negative 3 end exponent space straight x space 30 space right parenthesis space straight x space 400 over denominator 60 end fraction equals space 10 space straight N
