Question

A bullet of mass 0.02 kg is fired from a gun of mass 20 kg if the speed of the bullet is 150m/s, calculate the recoil speed of the gun.

Answer 1

Given:
mass of bullet 0.02 kg
speed of bullet =150m/s
mass of gun = 20kg
recoil speed of gun=?(let assume V)
Formula:
mass of bullet x speed of bullet= mass of gun X recoil speed of gun
0.02 x 150 = 20x v
v=0.02 x150/20
v=0.15 m/s
therefore, recoil speed of gun is 0.15 m/s

Answer 2

Answer:

Explanation:mass of bullet 0.02 kg

speed of bullet =150m/s

mass of gun = 20kg

recoil speed of gun=?(let assume V)

Formula:

mass of bullet x speed of bullet= mass of gun X recoil speed of gun

0.02 x 150 = 20x v

v=0.02 x150/20

v=0.15 m/s

therefore, recoil speed of gun is 0.15 m/s
