Why is the following situation possible? Emily challenges her friend David to catch a $1 bill as follows. She holds the bill vertically as shown in figure P2.29 with the center of the bill between but not touching David's index finger and thumb. Without warning, Emily releases the bill. David catches the bill without moving his hands downwards. David reaction time is equal to the average human reaction time. Avg human reaction time is .2s. Dollar bill is approx 15.5cm in length.
