I don't mean to sound like I'm egging you guys on, but i find it odd that questions involving much more complex and abstract physical theories are being answered, yet what would seem to me like a fairly simple problem, is causing so much trouble...or apathy, as the case very well may be...
perhaps http://www.phy.ntnu.edu.tw/java/collision2D/collision2D.html will help those who are almost on the right track.
It would seem to me that the equation would be something like this:
V2' = sqrt((cos θ * V2)^2 + (sin β * V1)^2))
V1' = sqrt((cos θ * V1)^2 + (sin &beta...
This is a little "high school", i know, but I'm trying to design a simple collision detection program and i need a few formulas, but i can't find them anywhere.
Here is the problem. I have two balls of equal size and mass in a frictionless, 2D environment. These balls have known velocities...
