Question

a bullet is fired into wall with a velocity of 50m/s. if the bullet stops at a depth of 10 cm inside the wall, find the retardatiom provided by the wall
​

Answer 1

Explanation:

Given-

u=50m/s

v=0m/s

s=10cm=10/100=0.1m

a=?

v^2=u^2+2as

0^2=50^2+2×a×0.1

0=2500+0.2a

-2500= 0.2a

a=-2500/0.2

a= -12500m/s^2
