Two joggers run at the same average speed. Jogger A cuts directly north across the diameter of the circular track, while jogger B takes the full semicircle to meet his partner on the opposite side of the track. Assume their common average speed is 2.70 m/s and the track has a diameter of 150 m. (a) How many seconds ahead of jogger B does jogger A arrive (b) How do their travel distances compare (c) How do their displacements compare (d) How do their average velocities compare
