Looking out the window at the apartment building across the street, Alex watches a potted cactus fall to the street 400 feet below. Because of the varying angle of depression ?, it seems to Alex that the pot first speeds up, then slows down. After how many seconds does the pot seem to be falling the fastest? When you answer this question, assume that Alex is 160 feet from the apartment building, and that a falling object (which has been dropped) will have traveled 16t 2 feet after falling for t seconds.
