Explanation

According to the law of conversation of mass–

  • The momentum of gun = The momentum of the bullet

[ Momentum = Mass × Velocity]

[ We know that 10 g = 0.01 Kg ]

{ Let the velocity of bullet be x }

  • 1 Kg × 5 m/s = 0.01 Kg × x m/s

  • 5 = 0.01 × x

  • x = 5/0.01

  • x = 5 × (100/1)

  • x = 500 m/s
