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

\theta=\sin ^{-1} \frac{3}{5}

to the x -axis while the object with mass M moves with a speed

\frac{3}{2} v

making an angle

\phi=\sin ^{-1} \frac{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

\frac{4}{5} v

. There are no external forces acting during the collision. The correct option is Two masses move on a collision path as shown. Before the collision the object with mass 2M moves with a speed v making

Two masses move on a collision path as shown. Before the collision the object with mass 2M moves with a speed v making

Options

AThe velocity of mass M , after the collision, is zero.
BThe centre of mass is moving along x -axis before the collision.
CThe velocity of centre of mass after the collision is $\frac{5}{2} v$
DThe total linear momentum of the system before the collision along x - axis is $\frac{5}{6} M v$

Correct answer

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