A bullet initially moving with a velocity of 20m/s strikes a target and comes to rest after penetrating a
distance of 0.01m in the target. Calculate the retardation produced by the target.

v=0m/s
u=20m/s
s=0.01m
v²-u²=2as
0-400=0.02a
a=-400/0.02=-20000m/s²
u=20m/s
s=0.01m
v²-u²=2as
0-400=0.02a
a=-400/0.02=-20000m/s²
