Homework Help: physics please help

Posted by taylor on Thursday, April 12, 2012 at 3:51pm.

a 10.0-g marble rolls to the left with a velocity of magnitude 0.400 m.s^-1 on a smooth, level surface and makes a head-on collision with a larger 30.0-g marble rolling to right with a velocity of magnitude 0.100 m.s^-1. If the collision is perfectly elastic,find the velocity of each marble after the collision.( since the collision is head-on, all the motion os along a line.)
