Ashton the ant is crawling on the still blade of a ceiling fan when the fan is turned on, causing Ashton to go for a ride. If Ashton sits on the fan blade at a distance of 0.80 m from the center of the fan and turns with a frequency of 1.2 Hz, a) how fast does Ashton spin? b) If Ashton slips off the spinning fan, describe the path he will take.
