1. The problem statement, all variables and given/known data 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 2. Relevant equations vf^2=vi^2+2(acceleration)(displacement) 3. 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.
