Thanks! This is not as simple as I thought:) Ive found a site that describes this kind of collision quite well. (http://www.myphysicslab.com/collision.html) I will give it another try to split the force somehow.

Sorry, I guess its my bad english. I approached it like this: There is a rigid body. You can push it but you can't rotate it. It gets hit by an other object and that adds v to its current velocity. That v stores some energy. I call that E_total(=1/2*m*v^2). Now I want to enable rotation. I...

Thanks! "Euler's equations" ...no. I forgot to say that its 2D not 3D so there's just one axis. "You seem to be using "v" both for velocity and for force ("vpush")." That was right:) τ = weight * v * r, not v*r because the force that generates that velocity is F = m*a (which is m*v if I...

Thanks! Ive tryed to calculate with forces and accelerations but I figured out that the eqvuations about torque and angular acceleration would only be corrent if the body was be rotating around a fixed axis:S Which is not the case. I don't know how can it work when I multiply the...

Homework Statement Im programming physics simulation. ...rigid body collision with ball. The ball is OK, but I have to push and rotate the rigid body. I have the contact point and the velocity(v) that I would add to the bodys current velocity if I wouldn't have to rotate it. So I need to...
