Homework Statement


The Drop Zone drops riders 27m from rest before slowingthem to a stop. How fast are they moving before they start slowing down?

vf=? vi=0, di=27m[up], df=om, displacement=27m[down], acceleration=9.8m/s^2[down] Air resistance is negligable

Homework Equations


vf^2=vi^2+2(acceleration)(displacement)

The Attempt at a Solution


I already figured this out and got the right answer(23 m/s), but in this question, the final velocity isn't 0m/s. That confuses me, because the final position is when they are on the ground- shouldn't the final velocity be 0m/s.

Key word: How fast are they moving before they start slowing down? If the riders have a velocity of 0 m/s on the ground, they have come to a complete stop.
You can't move from A to B at 0 m/s.

That makes sense. Thank you.
