Question

A bullet of mass 100 gram is fired from a gun of mass 20 kg with a velocity of 100 metre per second identify the velocity of recoil of the gun.Include a Proper Solution Also. ​

Answer 1

Step-by-step explanation:

Conservation of momentum

M(bullet)*V(bullet) = M(gun)* V(gun)

M(bullet) = 100 gram = 0.1 kg

M(gun)= 20kg

V(bullet) = 100m/s

find V(gun)

So, 0.1×100=20×V(gun)

V(gun) = 0.5 m/s
