From: Riccardo Maffei on 6 Apr 2010 08:01 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?

From: Riccardo Maffei on 16 Apr 2010 03:48 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.
