I wish to be able to know the angular and linear velocity it has after the collision.

Thanks in advanced.

Maybe this picture can help.

The speed the triangle has before the collision is 1m/seg and its mass is 2kg.

A further complication as in the above picture is if the angular from the first collision drives the tringle with another corner into the wall. That is where the fun stops. :P

Btw. are you sure you want no friction or just no air friction, as that would mean the corner hits the wall, slips along it and the side slams finally into the wall transforming any angluar momentum gained into an elastic collision, aka just a simple almost vertical bounce.

As you have seen speed and mass, play little importance to the geometric outcome of the collision. Any classical value will have the same angle and angular momentum (proportional to the speed). But for simplicity's sake get some unitary values.
