Alice on her scooter started from rest with a constant acceleration of $0\mathrm{.}41$ m$/$s$2$

north. How much time passed before she crossed the finish lineAlice, Bob, and Chris were all riding on things way too small for them. They had a race where

they all had a displacement of $100m$ north. They did not have the same starting velocity, but

they all left the starting line at the same time. I want to know who came in first, who came in

second and who came in third.

For clarity I will break this question into parts.
