Physics

At one instant a bicyclist is 40 m due east of a park's flagpole, going due south with a speed of 18 m/s. Then, 23 s later, the cyclist is 55 m due north of the flagpole, going due east with a speed of 12 m/s. For the cyclist in this 23 s interval, find each of the following.
(a) displacement
magnitude m
direction ° north of west

(b) average velocity
magnitude m/s
direction ° north of west

(c) average acceleration
magnitude m/s2
direction ° north of east
