Arace finishes at the same place as it started. the contestants start from rest and cross the finish line running. which one of the following is true about the average speed, the average velocity, and the average acceleration? note that the symbol ≠ means "not equal to".
a). average speed = 0 m/s, average velocity ≠ 0 m/s, average acceleration = 0 m/s2
b).average speed ≠ 0 m/s, average velocity = 0 m/s, average acceleration ≠ 0 m/s2
c).average speed = 0 m/s, average velocity = 0 m/s, average acceleration = 0 m/s2
d).average speed ≠ 0 m/s, average velocity = 0 m/s, average acceleration = 0 m/s2
e.)average speed ≠ 0 m/s, average velocity ≠ 0 m/s, average acceleration =0m/s^2
