At one instant a bicyclist is 36.0m due east of a park’s flagpole, going due south with a speed of 12.0m/s. Then 38.0s later, the cyclist is 36.0m due north of the flagpole, going due east with a speed of 12.0 m/s. For the cyclist in the 38.0s interval, what are the (a) magnitude and (b) direction of the displacement, the (c) magnitude and(d) direction of the average velocity and the (e) magnitude and (f) direction of the average acceleration?
