## Homework Statement

When an object falls through air, there is a drag force that depends on the product of the surface area, A (m2), and the square of the velocity, in (m/s). The equation is Fdrag = CAv2. The metric unit of force is the Newton, or (N). 1 N = 1 kg*m/s2. What are the units of the constant C?

and

Given the equation F =kA, where F is a force, k is a constant, and A is area, use unit analysis to determine the units of k.

N*s2/m4

N*s/m2

Answer choices for the second:

N*m2, or kg*m3/s2

N/m2, or kg/(m*s2)

m2/N, or m*s2/kg

N*m, or kg*m2/s2

I'm just having trouble starting this class out, and I'm sure this stuff is simple but I'm being thrown off by the steps and my teacher is pretty disorganized but his explanations are confusing me. I would love information and steps on how to solve this.
