There is a parlor trick in which person#1 hangs a dollar bill from their hand so that it dangles between the fingers of person#2. person#1 releases the bill, and person#2 must try to close their fingers in time to catch the bill before it falls completely through their fingers. the length of the bill is 15.6 cm and a typical person's reaction time is 0.20 seconds. the typical person will not be able to catch the bill. calculate how fast a person's reaction time would have to be to just barely catch the falling bill (assume that you can neglect air friction).
