⇒ Mass of the bullet = 10 g
⇒Velocity of the bullet = 150 m / s
⇒ Tie taken by the bullet to take rest when it strikes the wooden block = 0.03 s
TO FIND ;-
⇒ Distance of the penetration of the bullet = ?
⇒ Distance is also reffered to Displacement.
⇒Displacement is the shortest distance travelled by an object.
⇒Displacement = Velocity × Time
where average velocity is = (u + v) / 2
⇒ So displacement = [(u + v) / 2] × time
= [(150 + 0) / 2] × 0.03
= 2.25 m
Distance of the penetration of the bullet is 2.25 m
