There's a question that asks: if a wheel with 1.56 m/rad radius which reached a final velocity of 200 rad/min(or 10/3 rad/s) were slowed down with a constant torque of 10,000 NM being applied, how long would it take to stop the wheel. I can't seem to find how torque is related to this problem in anyway. I can solve it by doing the following:(adsbygoogle = window.adsbygoogle || []).push({});

Angular Displacement = (W^2-Wo^2)/(2*Angular Acceleration)

= (11.11rad^2/s^2)/(4.44rad/s^2)

= 2.5 rad

Angular Displacement = (t/2)(Wo+W)

=(2.5 rad) = (t/2)*(10/3rad/s)

=(2.5 rad)/(3.33rad/s)

= .75s = (t/2)

t = 1.5 s

But it may not be correct because I didn't use the radius or torque in that problem. Please respond with your ideas on how they could be applied to this problem.
