Question

A bullet of 5 gm is fired from a pistol of 1.5 kg. If the recoil velocity of pistol is 1.5 m/s, find the velocity of bullet.​

Answer 1

Answer:

A bullet of 5 gm is fired from a pistol of 1.5 kg. If the recoil velocity of pistol is 1.5 m/s, find the velocity of bullet. Velocity of bullet v1 =? Thus, velocity of bullet = 450 m/s, here negative sign with velocity of pistol shows that, bullet moves in the opposite direction of pistol.

Answer 2

Explanation:

M=mass of pistol

m= mass of bullet

V =recoil velocity

v=velocity of bullet

MV=-(mv)

=>1.5×1.5=(-5)v/1000

=>v=2.25×1000/(-5)

= - 450m/s

so VELOCITY of bullet is 450m/s in opposite direction of recoil
