    'cuz everyone i talked to swear it's parabola, but i'm skeptical.... i think it's an ellipse.

    :(

    I went with parabola, only because an ellipse comes back around like a circle, and a parabola would keep going straight down. It was my best guess anyways.

    I put parabola too...

    do you know what it means for a species to be "k-selected"??

    If a species is K-selected than its population is determined by the number of individuals the environment can support, i.e. if a particular environment can only support 50,000 individuals than that is the limit. In theory, the environment cannot support anymore individuals than that number.K-selected species are typically of higher order, like humans, show parental care, live a long life and have fewer offspring.
    The opposite of a K-selected species would be an r-selected species which tend to be of a low order, have many offspring at one time, short lives, no parental care. If I recall, r-selected populations are limited, for the most part, by predators.
    congrats on finishing the MCAT's ;)

    The Cornhusker State
    Parabola.
    The equation is y=Vi:thumbup:t - 1/2 at^2.
    y is the distance down.
    Vi:thumbup: is initial velocity heading down(zero)
    t is time
    a is acceleration
    The minus sign is in there because your going down. The grid (y and t) is set up as follows; y was going up and down (the vertical face of the cliff) and t is the time.

    It's just a basic high school algebra question. Peace Out. AEKDB.
