Question:

An athlete starts at point A and runs at a constant speed 6.0 m/s of around a circular track 100 m in diameter, as shown in Fig. P3.40. Find the x and y-components of this runner€™s average velocity and average acceleration between points

(a) A and B,

(b) A and C,

(d) A and A (a full lap).

(e) Calculate the magnitude of the runner€™s average velocity between A and B. Is his average speed equal to the magnitude of his average velocity? Why or why not?

(f) How can his velocity be changing if he is running at constant speed?
