Web4 okt. 2007 · A penny is dropped from the observation deck of the Empire State building (370 m above ground). With what velocity does it strike the ground? Ignore air resistance. asked by stephanie October 4, 2007 4 answers distance = 1/2 gt^2 Solve for time it takes for the penny to reach the ground. Then distance = 1/2 (Vinitial + Vfinal)t. Vinitial is zero. WebThe Empire State Building is about 1250 feet tall. If there were no air resistance on the penny as it fell, that would mean it would reach a maximum velocity of around 190-ish miles per hour when it hit the ground, taking just shy of 9 second to do so. That might sound really fast, but fortunately, it’s still not fast enough to kill someone.
