Question 6

Two particles $A\,$ and $B\,$ are moving on a smooth horizontal plane. The mass of $A\,$ is 2m and the mass of $B\,$ is $m$ . The particles are moving along the same straight line but in opposite directions and they collide directly. Immediately before they collide the speed of $A\,$ is $2u\,$ and the speed of $B\,$ is $3 u$ . The magnitude of the impulse received by each particle in the collision is $7mu2\displaystyle \frac{7mu}{2}$ .

a.

Find the speed of $A\,$ immediately after the collision.

b.

Find the speed of $B\,$ immediately after the collision.
