Homework Help: Sliding on the surface of a rough sphere (ploting theta in excel)

  1. Feb 19, 2009 #1
    1. The problem statement, all variables and given/known data

    I have determined the solution to my problem however now the problem asks me to plot theta as the block flies off the sphere when Mu k ranges from 0.0 to 0.5 in increments of 0.05 I don't know a great deal about working with Microsoft Excel. Well I do just not enough to know how to plot theta from this equation. The information is as follows.

    r = 1.5m

    [tex] V_0 = 3m/s [/tex]

    [tex] \mu [/tex] = 0.0 thru 0.5 in increments of 0.05

    [tex] \theta = ? [/tex]

    2. Relevant equations

    V^2 = \frac{(2 - 4 \mu^2) (e^{2\mu\theta} - cos(\theta)) - 6 \mu sin(\theta)} {(1 + 4\mu^2)}+ V_0^2 e^{2\mu\theta}

    V = rgcos(\theta)

    3. The attempt at a solution

    As for the attempt at the solution as I said I've already established the solution now I only need to plug into excel in order to solve for theta. Any help would be appreciated.

    You need to state the entire problem. I don't think anyone understands what you're trying to do.
