P = mv 
This is a momentum question: 
Momentum is always conserved so the momentum before and after a collision must be equal so:
The velocity of the two objects after they collide and dont stick together if no KE is lost is dependent on the mass of each of the objects by: 

Where i is initial and f is final meaning before and after the collision
