The ring rotates about point O and has the indicated angular motion. Also, at this moment, the collar moves downward following the ring with a speed of $5$m$/$s$,$ which increases to $8$m$/$s$^2,$ both measured with respect to the ring. Calculate the magnitude of the velocity and acceleration of the collar

The ring rotates about point O and has

the indicated angular motion. Also, at

this moment, the collar moves

downward following the ring with a

speed of $5\frac{m}{s},$ which increases to

$8\frac{m}{s^2},$ both measured with respect to

the ring. Calculate the magnitude of the

velocity and acceleration of the collar.
