Question

A bullet of mass 0. 01kg is fired with a velocity of 100m/s from a rifle of mass of 20kg. The recoil of the rifle is? ​

Answer 1

Answer:

0.01•100 = 20•recoil velocity

recoil velocity= 0.05

Answer 2

Answer: 0.5

Explanation:

To find any recoil velocity, we need to use this formula:

V = m 2 + v 2/ M

V = 0.01 x 100m/s / 20

V = 0.01 x 5

V = 0.5 m/s
