A hand-driven grinding wheel is a uniform 62-kg disk with a 41-cm radius. It has a handle of negligible mass 64 cm from the rotation axis. A compact 26-kg load is attached to the handle when it is at the same height as the horizontal rotation axis. Ignore the effects of friction.
(a) Find the initial angular acceleration of the wheel.
rad/s2
(b) Find the maximum angular velocity of the wheel.
rad/s
