7. An object falling in air experiences a drag force directly related to the square of the speed such that F = Cv2 (where C is a constant of proportionality). Assuming that the buoyant force due to air is negligible, the terminal velocity of this falling body is best described by the equation:
(The terminal velocity is the speed at which the object is in equilibrium).
a.) mg/C
b.) [ã (mg)] / C
c.) mg / ã (C)
d.) ã (mg/C)
e.) C/mg
