On Myth Busters it was determined that a penny dropped from thetop of the Empire State Building would reach a terminal velocity of64.4 miles per hour before hitting the ground. What is the heightof the building in feet needed for a penny with a mass of 2.5 gramsto reach a velocity of 46.7 miles per hour? Assume that no energyis lost from frictional drag. For the acceleration of gravity onthe Earth us 9.81 meters per second squared or 32.2 feet per secondsquared.
