At one instant a bicyclist is 60.0 m due east of a park's flagpole, going due south with a speed of 15.0 m/s. Then 11.0 s later, the cyclist is 50.0 m due north of the flagpole, going due east with a speed of 16.0 m/s. For the cyclist in this 11.0 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?
