Physics project help?

  1. Oct 7, 2014 #1
    1. The problem statement, all variables and given/known data
    I am supposed to use the data provided to plot py vs px vs time and use v1 px to plot v1 potential vs time.

    2. Relevant equations
    I am assuming I must use w=theta/time for py/px

    and this is where I am stuck is py/px the same think, or is there a separate equation for those? or is it the provided P in the project?

    3. The attempt at a solution
    This project has me really confused at the moment so this post may not make a lot of sense. I have uploaded the project.

    If I've understood correctly it actually says to plot..

    Py vs Px

    The table gives values for theta and P which you can convert to components Px and Py. See the diagram to the right of the table.

    So, to get to px and py, would I use an equation involving theta and P? Or how would I do that?

    Yes. I would suggest ...

    Px = P*Cos(theta)
    Py = P*Sin(theta)

    Try a spreadsheet?

    PS: I'm not at all familiar with heart monitoring!

    umm..does anybody know if my graph should look like this?

    Sorry had the wrong graph. (it should not look like the graph in this photo)
