PLEASE USE THE NUMBERS!
A 16-g coin that has a diameter equal to 1.7 cm is spinning at
12 rev/s about a fixed vertical axis. The coin is spinning on edge
with its center directly above the point of contact with the
tabletop. As you look down on the tabletop, the coin spins
clock-wise. Its moment of inertia about an axis through its
diameter is given in the figure below. Model the coin as a cylinder
of length L and...
