Question

a bullet is fired onto awall with a velocity of 30m/s . if the bullet stops at a depth of 10cm inside the wall ,find the retardation produced by the wall​

Answer 1

Answer: -4500m/s^2

Explanation:

v×v = u×u + 2×a×s

Assuming there is no distance between the wall and the gun

=> 0 = 900 + 0.2a

=> -900 = 0.2a

=> -900/0.2 = a

=> -9000/2 = a

=> -4500 = a

Ans = -4500m/s^2
