Calculating Coefficient of Restitution for Two Solid Balls Colliding

AI Thread Summary
The discussion revolves around calculating the coefficient of restitution (e) for two solid balls colliding. Initial calculations suggest e could be 1.75, but participants clarify that e must range from 0 to 1. One participant confirms their calculation of e as approximately 0.827, prompting others to request the detailed working behind this result. The conversation emphasizes the importance of showing calculations for educational purposes. Overall, the thread highlights common misconceptions and the need for accurate calculations in physics problems.

e is always from 0 to 1.
 
I found it 0.81 something! thanks

I make it a bit more. Please post your working.
 
e = 0.827 actually
 
Well done,
For the benifit of others stuck in the same way, please tell us how you got that.
