A large grinding wheel in the shape of a solid cylinder $\left(I=\frac{1}{2}MR^2\right)$  of radius 0.330 m is free to rotate on a frictionless, vertical axle. A constant tangential force of 250 N applied to its edge causes the wheel to have an angular acceleration of 0.940 rad/s2. What is the moment of inertia of the wheel?

A large grinding wheel in the shape of a solid cylinder  $\left(I=\frac{1}{2}MR^2\right)$  of radius 0.330 m is free to rotate on a frictionless, vertical axle. A constant tangential force of 250 N applied to its edge causes the wheel to have an angular acceleration of 0.940 rad/s2. If the wheel starts from rest, what is its angular velocity after 5.00 s have elapsed, assuming the
force is acting during that time?

A potter’s wheel having a radius of 0.50 m and a moment
