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.
I need help explaining this. Thank you.
Emily challenges her husband, David, to catch a $1 bill
as follows. She holds the bill vertically as in Figure P2.67,
with the center of the bill
between David's index finger
and thumb. David must catch
the bill after Emily releases
it without moving his hand
downward. If his reaction
time is 0.2 s, will he succeed?
Explain your reasoning. (This
challenge is a good trick you
might want to try with your
friends.)
