Urgent Help Needed: Can't Figure Out Homework Problem

In summary, the conversation discusses a homework problem involving a particle moving in a circular path. The problem has three parts and hints are provided for each part. The first part involves using the setup shown in the figure to find the distance the particle will cover in one complete cycle. The second part involves using the equation velocity = distance / time and substituting the distance found in the first part to find the velocity. In the third part, there appears to be a mistake in the original question and the solution should be straightforward if the mistake is corrected. The person asks for assistance and advises showing work to receive help.

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 ..
