A bullet is fired into a wall with a velocity of 50 M per second. If the Bullet stops at the depth of 10 cm inside the wall find find the retardation provided by the wall

Open in App

Solution

Given,

Initial velocity u = 50 m/s

Final velocity v = 0

Distance s = 10 cm

= 0.1 m

We know that,

v² = u² + 2as

a = -u² / 2s

a = -2500 / (0.2)

a = -12500 m/s²

So, retardation = 12500 m/s²
