A 500-lb flywheel is at rest when a constant 200 lb ?? ft couple M is applied at time t = 0. At t = 30 s the flywheel reaches its rated speed of 3000 rpm and the couple is removed. Assuming that the kinetic friction results in a constant couple of magnitude 12.5 lb ?? ft, determine

(a) The radius of gyration of the flywheel,

(b) The number of revolutions that the flywheel executes after the couple is removed and before it comes to rest.
