(3) 20 points. A corrupt congressman – or do I repeat myself? – stands at the edge of the roof of a tall building and throws a bag of $7.0 × 10^11 of your tax money away. He throws the massive bag of loot exactly horizontally with a speed of 5.5 m/s. The bag is caught by a debt-maddened and real-estate-crazed investment banker who is standing on the street below, 27 m away from the side of the building. Calculate the height of the building. (Assume there is no air resistance.)
The answer, in case anyone's curious, is 120 meters (to two significant figures). And 7.0×10^11 is 700 billion -- a nauseatingly familiar number, at this point.
