Question

A bullet going with speed 350 m/s enters a concrete wall and penetrates a distance of 5.0 cm before coming to rest. Find the deceleration.

Open in App
Solution

Initial velocity, u = 350 m/s
Final velocity, v = 0
Distance travelled by the bullet before coming to rest, s = 5 m
Acceleration, a=v2-u22s
a=0-35022×0.05=-12.2×105 m/s2
∴ Deceleration = 12.2 × 105 m/s2
