A mass ' M ' moving with velocity ' V ' along x -axis collides and sticks to another mass 2 M which is moving along Y -axis with velocity ' 3 ~V '. The velocity of the combination after collision is

Options

  1. AV 3 i +2 V j
  2. BV 2 i + V j
  3. CV 3 i -2 ~V j
  4. DV 2 i - V j

Correct answer

A. V 3 i +2 V j

Step-by-step solution

From law of conservation of linear momentum, aligned & M v i +2 M(3 v j )=3 M v & v i +6 v j =3 v & v = v 3 i +2 v j aligned
