At one instant a bicyclist is 47.0 m due east of a park's flagpole, going due south with a speed of 14.0 m/s. Then 30.0 s later, the cyclist is 47.0 m due north of the flagpole, going due east with a speed of 14.0 m/s. For the cyclist in this 30.0 s 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? (Give all directions as positive angles relative to due east, where positive is measured going counterclockwise.)
