Problem
A ceiling fan has blades that sweep out a circle of radius 0.60m. When set to its highest setting, the fan completes 1500 revolutions in 5min.
(i) Calculate the period of one revolution of a blade tip.
(ii) Determine the speed of the tip of a blade.
(iii) How many complete revolutions will the fan make in the next 2min at the same speed?
(iv) Find the total distance travelled by the tip of a blade during the entire 7min of operation described.
