So let's take the Grand Canyon. Drop the rock from my of 1800. Well, yeah. Single, too, you know, Plus, you know, minus 4.9 t squared. This is not my nature to to the questions. Peanut Zero. And Lena too. Zero Because we love you. When is it negative? Equal to negative for a plane. T squared the truth. 200 divided by 4.9. I wanted t squared reclines two is square 1800 more for one night. We know that it's positive because the rock was drought. No, I hope that makes sense.
