Actually this isn't a homework problem at all, and someone else added the homework tag!

comment Elastic collision in two dimensions
actually the problem is that I don't know how to start! I used those equations to eliminate three of the seven variables, but at the end I reached a rather long and ugly expression for which I didn't know how to convert it to the requested one. For this reason, I decided not to write my works. If you still want them, I can write them.

comment How can the Air friction force be applied to an object?
I simply didn't know how to apply Air friction force to the objects! All the problems I've solved before supposed that the Air friction could be omited...
