A 20 Kg slender rod pivoted at its center has a length of 6 m. A motor applied a torque of 2400 Nm on the rod to turn it from rest.(adsbygoogle = window.adsbygoogle || []).push({});

(a) Find the average power by the motor when the rod rotates an angle of 500 rad. _____________________

(b) Find the instantaneous power of the motor at the moment that the rod rotates an angle of 500 rad. ______________________

I am unsure how to start this.
