I missed a week of school because of a virus. During that week, I missed taking a lot of physics notes. When I returned, I received a problem from my teacher that he wants me to solve. I have the notes now but I don't understand them because they weren't taught to me, so may someone please help me with doing this problem.(adsbygoogle = window.adsbygoogle || []).push({});

1) a) Determine angular acceleration of a wheel, which has a velocity of 200 rad/min after rotating for 1.5s from start.

b) If the wheel has a rotational inertia of 5500 kgm2(squared), what would be its radius if 5000 N of forced had been applied?

c) If the same wheel, having reached a final velocity of 200 rad/min, were slowed down with a constant torque of 10,000 NM applied (with same radius), how long would it take to stop the wheel?

d.) How much force was applied?

e.) Determine the mass of the wheel. (the wheel is a solid disk)

Again, your help would be greatly appreciated.
