PLEASE HELP FAST!

i have 1 question on a homework.. its killing me.. its dues in a couple of hours!! someone HELP!

its 2 questions.. but i jus need the second one.. coz the seconds a part of the first..

HELP!!

1. A 4.73 g particle is moving at 3.2 m/s toward a stationary 10.2 g particle.

With what speed does the heavier parti_ cle approach the center of mass of the two particles? Answer in units of m/s.

2. What is the magnitude of the momentum of the lighter particle,relative to the center of mass? Answer in units of N s.

If you guys dont help me out.. im gonna die

HELP!! FAST!! I HAVE FEW HOURS LEFT!!

--------------------------------------------------

see i got the first part right.. its like..

momentum = total mass * velocity .. ie m1v1+m2v2/(m1+m2)..

but what about the 2nd part??

I DONT GET IT
