A mass ' m ' moves with a velocity v and collides inelastically with another identical mass. After collision the 1^ st mass moves with velocity v / 3 in a direction perpendicular to the initial direction of motion. Find the speed of the 2^ nd mass after collision

Options

  1. Av
  2. B3 v
  3. C2 v / 3
  4. Dv / 3

Correct answer

C. 2 v / 3

Step-by-step solution

m v=m v₁ 0= m v 3 -m v₁ v₁= 2 3 v
