I Don T Even Know Where To Start I M So Confused Find The Equation For The Angul
I don’t even know where to start.. I’m so confused… :/
1. Find the equation for the angular velocity ω 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 ω. If the moment of inertia of the flywheel is I and its initial angular velocity is ω0, find the equation for the angular velocity ω 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-Ω resistor and a 0.000001-F capacitor is driven by a voltage E(t)=sin 100t V. If the initial capacitor voltage is zero, determine the subsequent resistor and capacitor voltages and the current.
