## Homework Statement

If the effects of air acting on falling raindrops are ignored, then we can treat raindrops as freely falling objects. Rain clouds are typically a few hundred feet up in the sky. Estimate the speed which raindrops would strike the ground if they were freely falling objects.

## Homework Equations

vf^2=vo^2+2as

vf-TARGET

v0- 0

s- 200

a- -9.8

## The Attempt at a Solution

Ok I know the answer, but I don't understand something. What I did was put all my knowns into the equation. Then this is what it looks like.

vf^2= -3920

That is obviously unreal. Then I see that there is a problem with the acceleration. WHY? I thought acceleration of freely falling objects was -9.8.
