On 4.4 are you supposed to draw from the appex or the entire parabola? Also, how do you figure out the gravitational pull for the acceleration graph?

It won't be an entire parabola, but you don't draw from the apex. We worked this problem (or most of it) during tribe day in a couple of classes. The screen shots are on the website.

Well, the first thing you need to do is draw your "ups" triangle in the bow tie. You know the area of the triangle (70m). You know the height (Vo). The base will be the time it takes the phone to get to the apex.
