well, your answer for part d both enlightened and further confused me, but point P is on the surface of the table where the bottom of the ball rests on it (before it is struck with the cue).
good to know I got the rest of it right ;)
Well, I know it is rotating slower than the top, and in the reverse direction... Does the rotational velocity of that point go to 0 when you add the translational and rotational velocities? This one part rotates faster than the other part has always been confusing to me...
rotational motion -- billiard ball problem
I've been struggling with an AP physics free resposne problem. I have what I hope to be the right answer, but I'm not sure.
Heres the question:
A billiard ball has mass M, radius R, and moment of inertia about the center of mass Ic = 2/5 * M *...
