Making a Model

  1. Feb 26, 2006 #1
    The table describes the flight of a toy glider launched from a tower on a hilltop.
    The values for height indicate the number of metres above or below the top of the hill.

    I have to find an algebraic model that gives height as a function of time.

    How do I do that?
    I have no idea where to start.

    Any help would be appreciated!
    Thanks :)

    This can be exactly modeled by a polynomial. Try graphing it.

    1. Try a linear model: h= at+ b. Use the first two data points to determine a and b. Does that work for the other points?
    If not
    2. Try a quadratic model: h= at2+ bt+ c. Use the first three data points to determine a, b, and c. Does that work for the other points?
    If not
