At one instant a bicyclist is 45.0 m due east of a park's flagpole, going due south with a speed of 12.0 m/s. Then 21.0 s later, the cyclist is 45.0 m due north of the flagpole, going due east with a speed of 12.0 m/s. For the cyclist in this 21.0 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 meaured going counterclockwise.)
