At everyday speeds, drag force is proportional to the speed of the object raised to the power:
AOne
BSix
CTen
DTwo
Answer & Solution
Correct answer: D. Two
1. Doubling the speed does far more than double the drag.
2. The relationship is quadratic in speed.
3. So drag is proportional to the square of the speed.
