Ignore air resistance. Assume a free falling object accelerates at [math] feet per second. (On Earth, of course, [math].) Your answers will be mathematical expressions involving [math], [math], and [math].
You toss a rock up vertically at an initial speed of [math] feet per second and release it at an initial height of [math] feet. The rock will remain in the air for seconds.
It will reach a maximum height of feet after seconds.
