A solid sphere of mass M$=2$kg and radius R$=0\mathrm{.}2$m is initially at rest at the top of a ramp of height H$=1\mathrm{.}2$m and angle $=30.$ The sphere released and rolls without slipping to the bottom of the ramp. The moment of inertia of the sphere is I$=25$MR$2.$

It takes t$=1\mathrm{.}17$s for the sphere to roll to the bottom of the ramp.

What is the net torque acting on the sphere as it rolls down the ramp? Define clockwise $$ as positive.
