➡ A machine gun has a mass of 15 kg. It fires 100 gms bullets at the rate of 40 bullets per minute at a speed of 60m/s what force is required to keep the machine gun in position .

$\huge\bold{\mathtt{\underline{\underline{\purple{ANSWER}}}}}$

✤ GIVEN :

☯ Mass of gun = 15 kg

☯ Mass of each bullet = 100 g = 0.1 kg

☯ Speed of bullet = 60 m/s

✤ TO FIND :

Force

✤ SOLUTION :

☯ Number of bullets per second

= $\sf \dfrac{60}{60}\:=\:1$

• Now , Force will be -

⏹ FORMULA USED → $\sf{\red{Force\:=\:n \times \dfrac{mv}{t}}}$

❥ $\sf Force\:=\: 1 \times \dfrac{15 \times 60}{1}$

❥ $\sf Force\:=\: 900\:N$

${\red\bigstar\large\bold{\mathrm{\underline{\green{FORCE\:=\:900\:N}}}}}$
