Question

bullet of mass 10g is fired with a rifle. The bullet takes 0.003s to move through its barrel and leaves it with a

velocity of 300m/s. What is the force exerted on the bullet by the rifle.

Answer 1

[0010001111]... Hello User... [1001010101]
Here's your answer...

The mass of the bullet (m) = 0.01 kg
Its initial velocity (u) = 0, as it was at rest before being fired.
Its final velocity (v) = 300 m/s
Time taken = 0.003 s
$a = \frac{v - u}{t} \\ = \frac{300 - 0}{0.003} \\ = \frac{300 \times 1000}{3} \\ = 100000$
Acceleration of the bullet is 100000 m/s²
Force = mass × acceleration
= 0.01 kg × 100000 m/s²
= 1000 N
The firce exerted by the rifle on the bullet will be 1000 N.
