Two masses move on a collision path as shown. Before the collision the object with mass 2M moves with a speed v making an angle = ⁻¹ 3 5 to the x -axis while the object with mass M moves with a speed 3 2 v making an angle = ⁻¹ 4 5 with the x -axis. After the collision the object of mass 2 M is observed to be moving to the right along the x -axis with a speed of 4 5 v . There are no external forces acting during the c

Options

  1. AThe velocity of mass M , after the collision, is zero.
  2. BThe centre of mass is moving along x -axis before the collision.
  3. CThe velocity of centre of mass after the collision is 5 2 v
  4. DThe total linear momentum of the system before the collision along x - axis is 5 6 M v

Correct answer

B. The centre of mass is moving along x -axis before the collision.
