I am trying to find the initial velocity of a soccer ball ,(adsbygoogle = window.adsbygoogle || []).push({});

but I found this equation and do not understand how it came about:

This is supposed to give you the velocity of the ball right after its kicked, using the mass of your leg, velocity of your leg, and the coefficient of restitution [e].

Any help appreciated!

Thanks
