None.

The Attempt at a Solution

The answer key says that the answer is the bus coming to a stop. I think this is the answer because the wheels of the bus are slowing down. Is this the right answer, because a lot of people in my class thought that the answer was the Earth revolving the sun, even though the Earth revolves around the sun in an elliptical orbit and not a circular one.

The bus option is not clear as it should have probably stated the bus' wheels while coming to a stop. From the question however you should have been able to guess from the term non-circular motion. Of course, the Earth being in an elliptic orbit means its not in uniform or non-uniform circular motion since the common condition for both is that there must be circular motion.

So you're saying that the answer is B? Or is it just a bad question?

 

[Kurdt]

The answer is A and the question could have been clearer.
