At one instant a bicyclist is 40.0 m due east of a park’s flagpole, going due south with a speed of 10.0 m/s.Then 30.0 s later, the cyclist is 40.0 m due north of the flagpole, going due east with a speed of 10.0 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?

Question
At one instant a bicyclist is 40.0 m due east of a park’s flagpole,
going due south with a speed of 10.0 m/s.Then 30.0 s later, the
cyclist is 40.0 m due north of the flagpole, going due east with a
speed of 10.0 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?
