If the $3-$lb solid sphere is released from rest when $=30,$ determine its angular velocity when $=0,$ which is the lowest point of the curved path having a radius of $11\mathrm{.}5$ in$.$ The sphere does not slip as it rolls.

$=17\mathrm{.}15ra\frac{d}{s}$

$=18\mathrm{.}13ra\frac{d}{s}$

$=21\mathrm{.}5ra\frac{d}{s}$

$=15\mathrm{.}17ra\frac{d}{s}$
