Hey I'm making some kind of simulation... (in game maker) Ball collisions, ball to wall(friction)etc.
So I'm asking: how do i calculate rotational speed if i know r, mass, and distance to where is force being applyed?
I know that moment of inertia for a ball is 2/3*m*r2 and have no idea how to use it...
friction is also a problem.. i don't know how to calculate friction with wall if i know friction koeficient...
(sry for any mistake, I am not from england)
