A particle of mass m moving with velocity v collides with a stationary particle of mass 2 ~m . After collision, they stick together and continue to move together with velocity

Options

  1. Av
  2. Bv 2
  3. Cv 3
  4. Dv 4

Correct answer

C. v 3

Step-by-step solution

Applying conservation of linear momentum P _ i = P _ f ( P = mv ) m v₁+2 m v₂=(m+2 m) v^ m v^1+2 m 0=(3 m) v^ mv =3 mv ^ v ^ = v 3
