A 17g object moving to the right at 32 cm/s overtakes and collides elastically with a 35g object moving in the same direction at 12 cm/s. Find the velocity of the slower object after the collision. Answer in cm/s.

B) Find the velocity of the faster object after the collision. Answer in cm/s.

2. Relevant equations

(ma1*va1)+(mb1*vb1)=(ma2*va2)+(mb2*mb2)

.5((ma1*va1)^2+(mb1*vb1)^2)=.5((ma2*va2)^2+(mb2*mb2)^2)

3. The attempt at a solution

(17*32)+(35*12)=(17*x)+(35*y)

And since I have two variables, I'm not sure how to solve for either of them. I tried solving for one in terms of the other...

(928-17x)/35=y

But that wasn't the answer my instructor was looking for. Thanks so much for any help you can provide.
