Question

If a gun of mass 40 kg fires a bullet of mass 8g with a velocity of 100ms . The recoil velocity of gun is ...​

Answer 1

Answer:

0.02 m/s

Explanation:

Given,

Mass ( gun ) = 40 kg

Mass ( bullet ) = 8 g = 0.008 kg

Velocity ( bullet ) = 100 m/s

To find : Recoil velocity of gun = ?

Formula : -

Recoil velocity of gun

= [ Mass ( bullet ) × Velocity ( bullet ) ] / Mass ( gun )

= [ 0.008 × 100 ] / 40

= 0.8 / 40

= 0.02 m/s

Therefore, The recoil velocity of gun is 0.02 m/s.
