    hint for part (a)

    use the setup in the figure

    hint for part(b)

    you know that velocity = distance / time .. your time here is T (time for one complete cycle) so find the distance that the particle will cover during that time (i.e distance of one cycle) and substitute ..



    hint for part (c)

    hmmm .. i think your original questions is missing an r .. it should be in part (a) that you prove r = r cos(theta) i + r sin(theta) j ?? .. if there was such a mistake then this part should be straight forward ..




    show your work , so if you got stuck at some point we can help ..
