Question

estimate: you throw a frisbee. Ignoring the translational motion of the frisbee entirely, and concentrating only on the spin you give the frisbee by snapping your wrist just before you release it, estimate

the frisbee's angular acceleration during the throw
the torque you exert on the frisbee during the throw
the frisbee's rotational kinetic energy at release

As in prior estimates, you're to make no assumptions about the time involved. Suggested quantities to make assumptions about are: the initial and final angular velocities of the frisbee, the angular displacement of the frisbee during the wrist snap, and the mass of the frisbee.
Assumed and calculated quantities should have no more than 2 SF, and all should be justified. Explain your work as you go.
We don't cover rotational kinetic energy until next week, so it's ok to omit the last part of the estimate from your first response, then fill it in next week, after the deadline. Or you can read ahead and figure out the kinetic energy before the deadline.
