Question

Which describes the average velocity of a unicycle going around in circles?

O A. The slope of the acceleration vs. time graph,
O B. The average acceleration divided by the time.
O c. Every time the unicycle returns to its starting point, the average
velocity equals zero.
D. The total displacement divided by the time​

Answer 1

I would say C as the answer.

Answer 2

Step-by-step explanation:

This is not a nice question. On the surface, it looks like C and D are both correct.

Coming back to the starting point makes the displacement = 0. That means that the velocity is also 0.

On the other hand, the total displacement when going in a circle can also be zero.

To me the best answer is probably D, but I wouldn't be surprised if the poser of the question thinks it is C. I would answer D but hold your nose when you do it.
