Well I'm back. LOL Yet another question regarding my homework problem. Here's the problem: A ball of radius 0.370m rolls along a horizontal table top with a constant linear speed of 3.20m/s. The ball rolls off the edge and falls a vertical distance of 2.70m before hitting the floor. What is the angular displacement of the ball while it is in the air? (Assume there is no slipping of the surfaces in contact during the rolling motion.) So I assumed it would be helpful to determine the time the ball is in the air which I did. Calculating t = 0.742s. Since the linear speed is constant, both omega initial and omega final are equal to 3.20m/s. Am I correct in thinking this? This is where I've reached a halt. I'm unsure of what to do next. Any help to point me in the right direction would be greatly appreciated. Thanks in advance for any help provided.
