# At one instant a bicyclist is 38.0 m due east of a park's flagpole, going due south with a speed of 14.0 m/s. Then 23.0 s later, the cyclist is 38.

At one instant a bicyclist is 38.0 m due east of a park's flagpole, going due south with a speed of 14.0 m/s. Then 23.0 s later, the cyclist is 38.0 m due north of the flagpole, going due east with a speed of 14.0 m/s. For the cyclist in this 23.0 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.)
