At one instant a bicyclist is 25 m due east of a park's flagpole, going due south with a speed of 9 m/s. then, 27 s later, the cyclist is 60 m due north of the flagpole, going due east with a speed of 13 m/s. for the cyclist in this 27 s interval, find each of the following. (a) displacement magnitude 1 m direction 2 ° north of west (b) average velocity magnitude 3 m/s direction 4 ° north of west (c) average acceleration magnitude 5 m/s2 direction 6 ° north of east.
