Hello, im having a problem calculating the angular velocity of a bouncing ball. At first this ball is thrown a distance and then hits the ground. Before it hits the ground it has no angular velocity. After it hits the ground it gets an angular velocity. I have the inertia of the ball and coordinates of the ball travelling. The whole proces I have on a video which was handed with the assignment. 3. The attempt at a solution I have some teories of using the impulse between the ball and the floor but nothing seems to working quite well. Also I would have thought that the friction should have been given. I would really appreciate if you guys could just give me some ideas. Thx for the help.
