The drag force pushes opposite your motion as you ride a bicycle. if you double your speed, what happens to the drag force?

The drag force goes up by a factor of 4

Explanation:

The Drag Force equation is:

(1)

Where:

is the Drag Force

is the Drag coefficient, which depends on the material

is the density of the fluid where the bicycle is moving (air in this case)

is the transversal area of the body or object

the bicycle's velocity

Now, if we assume , and do not change, we can rewrite (1) as:

(2)

Where groups all these coefficients.

So, if we have a new velocity , which is the double of the former velocity:

(3)

Equation (2) is written as:

(4)

Comparing (2) and (4) we can conclude the Drag force is four times greater when the speed is doubled.

i believe the answer is a

the components of a vector are the parts of the vectors that are to each other.
