You toss a rock up vertically at an initial speed of 39 feet per second and release it at an initial height of 6 feet. the rock will remain in the air for seconds. it will reach a maximum height of feet after seconds. ignore air resistance. this is the general version of the previous problem. again, ignore air resistance. assume a free falling object accelerates at g feet per second. (on earth, of course, g = 32.) your answer will be mathematical expressions involving g, v, and h. you toss a rock up vertically at an initial speed of v feet per second and release it at an initial height of h feet. the rock will remain in the air for seconds. it will reach a maximum height of feet after seconds.
