n early method of measuring the speed of light makes use of a rotating slotted wheel. A beam of light passes through one of the slots at the outside edge of the wheel, travels to a distant mirror, and returns to the wheel just in time to pass through the next slot in the wheel. One such slotted wheel has a radius of 6.0 cm and 850 slots at its edge. Measurements taken when the mirror was l = 500 m from the wheel indicated a speed of light of 3.0 105 km/s.

(a) What was the (constant) angular speed of the wheel?
rad/s

(b) What was the linear speed of a point on the edge of the wheel?
m/s
