hey is this true even when two balls meet?
is this the right way to get the answer?


To get the final angle:
AngleIncidence = AngleReflection
AngleIncidence = (180° + InitialAngle) - (NormalAngle)
AngleReflection = (NormalAngle) - (FinalAngle)
Solving for FinalAngle:
180 + Init - Norm = Norm - Final
180 + Init - 2 Norm = - Final
Final = 2 * Norm - 180 - Init


is the InitialAngle the angle between the two balls and if so does it matter if i get the angle from A to B first or B to A first?



i have the angle between B and A of 134 by 314 degrees when touching each other

ball B is moving at 23 degrees
ball A is moving at 229 degrees

how do i get the right reflextion angle for each ball?

thanks verry much
