A particle of mass m moving with velocity v collides with a stationary particle of mass 2 m . The speed of the system, will be

Options

  1. A3 v
  2. Bv 2
  3. Cv 3
  4. D2 v

Correct answer

C. v 3

Step-by-step solution

According to conservation of momentum gathered m₁ v₁+m₂ v₂= (m₁+m₂ ) v^ m v+2 m 0=(m+2 m) v^ gathered So, v^ = v 3
