Derivative problem

  1. Jan 23, 2006 #1
    A electron moving along the x axis has a position given by
    x = 10te^-1.9t m, where t is in seconds. How far is the electron from the origin when it momentarily stops?

    i not exactly sure how to solve for t, since it has 2 t variables in the problem. any help would be appreciated.

    Google for the product rule.

    d(e^x)/dx = e^x.
    I think this is where you are stuck.
