Homework Help: Terminal velocity for big objects

  1. Jan 30, 2009 #1
    1. The problem statement, all variables and given/known data

    The drag force on large objects such as cars, planes, and sky divers moving through air is more nearly Fdrag = -bv^2.

    For this quadratic dependence on v, determine a formula for the terminal velocity vTerm, of a vertically falling object.

    Express your answer in terms of the variables m, b, and appropriate constants.

    2. Relevant equations
    Vterm = mg/b


    3. The attempt at a solution

    No idea how to begin this question.

    At terminal velocity, the force of drag is equal to the gravitational force.

    'b' is a characteristic dimension, such as the distance from front to rear bumper for an automobile attempting to fly.

    You managed to leave out a square root in your equation.
