Question

.A gun of mass 30 Kg fires a bullet of mass 30 g with a muzzle velocity 300 m/s.
Find the recoil velocity of gun?

Answer 1

Question :

A gun of mass 30 Kg fires a bullet of mass 30 g with a velocity 300

m/s.Find the recoil velocity of gun?

Answer :

Given :

• M = mass of gun = 30 kg

• m = mass of bullet = 0.03 kg

• v = velocity of bullet = 300 m/s

To find :

• V = Velocity of gun = ??

Formula to be used :

V = - mv / M

Solution :

V = [ (- 0.003 )(300) ]/ 30

V = - 0.003 × 10

V = - 0.03

So recoil velocity of gun = - 0.03 m/s .
