**1. The problem statement, all variables and given/known data**

At one instant a bicyclist is 37 m due east of a park's flagpole, going due south with a speed of 14 m/s. Then, 37 s later, the cyclist is 37 m due north of the flagpole, going due east with a speed of 14 m/s. 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? (Give all directions as positive angles relative to due east, where positive is measured going counterclockwise.)

**3. The attempt at a solution**

A) root (37^2 + 37^2) = 52.33

B) tan-1 (37/37)= 45 so 135 degrees

can someone tell me how to calculate the other questions??
