u1=(m1+m2)•v1/(m1+m2)
u2=2•m1•v1/(m1+m2)
A 50-g ball collides elastically with a 290-g ball that is at rest. If the 50-g ball was traveling in the positive x-direction at 4.75 m/s before the collision, what are the velocities of the two balls after the collision?
290-g ball: magnitude m/s ?
50-g ball: magnitude m/s ?
How do I do this? :/

I don't understand what I am doing wrong
I plugged in for the 1st one:
(.05+.290)(4.75)/(.05+.290)
and for second one:
2(.290)(4.75)/(.05+.290)
but I get wrong answers!
