1.Find the equation for the angular velocity in Problem 15, assuming that the retarding torque is proportional to w.
This is problem 15: A rotating flywheel is being turned by a motor that exerts a constant torque T. A retarding torque due to friction is proportional to the angular velocity . If the moment of inertia of the flywheel is I and its initial angular velocity is 0, find the equation for the angular velocity as a function of time. [Hint: Use Newton's second law for rotational motion, that is, moment of inertia angular acceleration = sum of the torques.]
Note : w = d0/dt **** d0 is d- theta
3.An RC circuit with a 1- resistor and a 0.000001-F capacitor is driven by a voltage E(t)=sin100tV.If the initial capacitor voltage is zero, determine the subsequent resistor and capacitor voltages and the current.
