According to an article in the boston Globe, a man named Paul Tavilla stood at the base of Boston's 60-story John Hancock Tower, his neck bent back, mouth open, as grapes were dropped from the observation tower, 600ft above. On his 70th try, he caught one in his mouth as a crowd of 150 spectators burst into appleause. If a grape weighs mg = 0.02 lb and the air friction is proportional to the speed of the grape with a coefficient of resistance 0.00002, what is the speed of the grape when Mr. Tavilla catches it?
