(another tomato/skyscraper problem.) you are looking out your window in a skyscraper, and again your window is at a height of 450 feet above the ground. this time, however, you know that the tomato was dropped (so v0 = 0), but you did not see it dropped so you do not know when it was dropped. you measure that it takes exactly 2 seconds from the time the tomato passes your window until it hits the ground. from what height did it fall? give your answer as a decimal approximation with units.
