Q. Kepler's First Law: What are the values of r1 and r2 (in AUs) at when the planet is at far right? (Please separate the answer for r1 and r2 with a comma)

Q. At one instant a bicyclist is 43 m due east of a park's flagpole, going due south with a speed of 12 m/s. Then 22 s later, the cyclist is 43 m due north of the flagpole, going due east with a speed of 12 m/s. For the cyclist in this 22 s interval, what are (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 are measured going counterclockwise.)
