Two particles A A\,A and B B\,B are moving on a smooth horizontal plane. The mass of A A\,A is 2m and the mass of B B\,B is mmm. 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 A\,A is 2u 2u\,2u and the speed of B B\,B is 3u3u3u. The magnitude of the impulse received by each particle in the collision is 7mu2\displaystyle \frac{7mu}{2}27mu.
Find the speed of A A\,A immediately after the collision.
Find the speed of B B\,B immediately after the collision.
