Hi to everybody.
We suppose to have three balls of center C1, C2, C3 with different rays R1,
R2,R3
and different masses m1, m2,m3.
Is v1,v2,v3 the initial speeds.
The motion happens on a straight line.

O O O
------------------------------------------------
C1 C2 C3

Instantly t=0 the balls are to contact with given speed.
You asks the speeds after the bump.
How to do?

I have resolved the problem for a succession of increasing or decreasing
speed.
How to do for any speed?
Excuse for the non perfect English.
Thanks.
