Then, 13 s later, the cyclist is 45 m due north of the flagpole, going due east with a speed of 13 m/s. For the cyclist in this 13 s interval what is the displacement (m) and direction north of west, average velocity (m/s) and direction north of west and the average acceleration and direction north of east
