A bullet of mass 20 g moving with a speed of 120 m/s hits a thick muddy wall and penetrates into it. It takes 0.03 s to stop in the wall find the force exerted by the bullet on the wall,

Text Solution

Verified by Experts

From newton.s third law, the force exerted by the bullet on the wall is also 80d N, in direction of the velocity.
