Question

find the average recoil force on a machine gun that is firing 150 bullets per minute , each with a speed of 900 ms^-1.mass of each bullet is 12 _g

Answer 1

Dear Student ,
Here the average recoil force is ,
$F=\frac{m\times n\times v}{t}=\frac{12\times {10}^{-3}\times 900\times 150}{60}=27N$
