what is deference between center of percussion(Cop) vs radius of gyration?
I understand that radius of gyration(K0) is the
concentrated mass in rotation so it is equal that int_r^2 dm =
m*K0^2
so i think it is equal cop = Ko but it is not.
why?

The 50-kg flywheel has a radius of gyration about its center of
mass of ko= 250mm. It rotates with a constant angular velocity of
120rev/min before the brake is applied. If the coefficient of
kinetic friction between the brake pad B and the wheel’s rim is ?k=
0.5, and a force of P = 300 N is applied to the braking mechanism’s
handle, determine the time required to stop the wheel.
