Terminal velocity for big objects

[cleverfield]

Homework Statement

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.

Homework Equations

Vterm = mg/b

The Attempt at a Solution

No idea how to begin this question.

 

[m.e.t.a.]

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

$$F_{drag}=-bv^2=...$$

'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.
