Question

a bullet fired at the target with a velocity of 100 metre per second penetrates 1 metre into it if the bullet is fired at a similar target with a thickness 0.5 then it will emerge from it with the velocity of​

Answer 1

Answer:

Velocity=100m/s

Thickness of bullet=0.5 m

Thickness of the target in which it penetrates=1m

Momentum =m*v

100*0.5 =v*1

50=v

Hence the velocity with which it penetrates =50m/s
