Homework Help: Circular Motion

    1. The problem statement, all variables and given/known data

    2. Relevant equations
    None.


    3. 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?

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