Question

A gun of mass 10kg fires a bullet of mass 0.05kg with a speed of 200m/s calculate the velocity of recoil of the gun​

Answer 1

Answer:

According to law of conservation of momentum:

mass of gun x its recoil velocity = mass of bullet x its velocity

10kg x recoil velocity = 0.05kg x 200m/s

10kg x recoil velocity = 10kg.m/s

recoil velocity = 1 m/s

Answer 2

Answer:

Recoil velocity = 1 m/s

Explanation:

Law of conservation of Momentum:

mass of gun x recoil velocity = mass of bullet x its velocity

10kg x recoil velocity = 0.05kg x 200m/s

10kg x recoil velocity = 10kg.m/s

Recoil velocity = 1 m/s                                 ANSWER
