Everybody knows that if a ball hits an equal mass ball the one that was moving will stop and the other on which was stopped will move, this is the funtioning of newtons craddles.(adsbygoogle = window.adsbygoogle || []).push({});

My question is rather simple:

If a 1kg billiard ball at a speed of 1 m/s hits a 2kg still ball, with what speed will rebound the 1 kg ball? what speed will acquire the 2kg ball? what formula have you used to solve this problem?
