Question

A bullet of mass 10g is fired from a gun of mass 6 kg with a velocity of 300m/s

Answer 1

Answer:

If we have to find momentum of the bullet so the momentum of bullet will be 3kgm/s

Answer 2

Correct Question:

• A bullet of mass 10g is fired from a gun of mass 6 kg with a velocity of 300m/s. what is the recoil velocity of gun?

Given:

• Mass of Bullet = 10g
• Velocity of Bullet = 300 m/s
• Mass of gun = 6 kg

To Find:

• Recoil velocity of Gun?

Solution:

Mass of bullet is 10g

=> 1kg = 1000 g

=> kg = 10/1000

=> kg = 0.01 kg

$\bigstar{\underline{\underline{\boxed{\sf{ \green{Momentum_{(Bullet)} } = \blue{Momentum_{(Gun)} } }}}}}$

$\bigstar{\underline{\boxed{\sf{ Momentum = Mass \times Velocity }}}}$

After substituting values,

➙ Momentum (bullet) = Momentum (Gun)

➙ m × v = m × v

➙ 0.01 × 300 = 6 × v

➙ 3/6 = v

➙ v = 0.5 m/s

Hence,

• The Recoil Velocity of gun is 0.5 m/s.
