Question

A bullet of mass 100 gram is fired from a gun of mass 20 kg with a velocity of 50 metre per second identify the velocity of recoil of the gun

Answer 1

Answer:

0.25 m/s

Explanation:

As V = mv/M

where m = mass of bullet , v = velocity of bullet and M = mass of gun

And V = recoil velocity now we will convert mass of bullet into kg

m=0.1 kg

Therefore

V = mv / M

V = 0.1×50 / 20

V = 5/20

therefore V = 0.25 m / second
