⭐hey there !!

Given that:

v=150 m/s

s=3.2 cm = 0.032 m

now when it penetrates then its final velocity(v) = 0

now using 3rd equation of motion

i.e v² = u² + 2as

now, a = (v²-u²)/2s = (0 - 22500)/2×0.032

= -351562.5 m/s²

here negative sign denotes retardation ...I.e acceleration is in opposite direction to the direction of motion.
