A bullet of mass 10 g is fired from a gun of mass 1 kg . If the recoil velocity is 5 ~m / s , the velocity of the muzzle is

Options

  1. A0.05 ~m / s
  2. B5 ~m / s
  3. C50 ~m / s
  4. D500 ~m / s

Correct answer

D. 500 ~m / s

Step-by-step solution

From law of conservation of momentum aligned & M V=m v & 1 5=10 10⁻³ v & v=500 aligned
