On the game show Wheel of Fortune, the contestants take turns spinning a large wheel to win prizes. When one of the contestants spins the wheel, it goes from rest to a full speed of 22 rev/minrev/min in one eighth (1/8) of a complete rotation. a.) Once it has reached full speed, what is the angular velocity of the wheel in rad/sec? b.) What is the angular acceleration of the wheel in rad/sec2 c.) How long does it take the wheel to reach full speed? d.) If the wheel is a large, solid disk with radius of1.6 mm , and a mass of 111 kgkg , then what is its rotational inertia? The wheel lies flat on the floor, and spins about an axis through its center, with the axis perpendicular to the floor. e.) Assuming the contestant grabbed on to the edge of the wheel in order to spin it, then how much force did she apply to make it spin as described above? (Assume that the force is applied perpendicular to the edge of the disc.)
