1. The problem statement, all variables and given/known data A 11 g coin of diameter 1.9 cm is spinning at 15 rev/s about a vertical diameter at a fixed point on a tabletop. A coin is a solid cylinder of length L and radius R, where L is negligible compared to R. Its moment of inertia is 1/4MR^2. (A)What is its angular momentum about a point on the table 10 cm from the coin? For the following questions, assume the coin spins about a vertical diameter at 15 rev/s while its center of mass travels in a straight line across the tabletop at 5 cm/s. (B)What is the angular momentum of the coin about a point on the line of motion of the center of mass? (C)What is the angular momentum of the coin about a point 10 cm from the line of motion? 2. Relevant equations L=r*p L=I *omega 3. The attempt at a solution I tried L= r*p, where p equals m*v, and r was .1m, m was .011kg, and v was omega times the radius of the coin, which gave me an angular momentum of 9.85e-4. I know this isn't right. For B should I add the angular momentum and the linear momentum? And for C, if I can figure out A, I might be able to do that with C.
