Question

How to solve problems on collisions with rotation?

Answer 1

Answer:

Place the ice cubes on the surface several centimeters away from each other.

Flick one ice cube toward a stationary ice cube and observe the path and velocities of the ice cubes after the collision.

Try to avoid edge-on collisions and collisions with rotating ice cubes.

Answer 2

Answer:

The collision is fully elastic. The exercise is then to calculate the CoM velocity and rotation speed after the collision. A standard solution to this is to set up two equations: angular momentum conservation about the axis perpendicular to v0 and through the collision point.
