Chapter 2, Problem 69AP
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.)

seconds, the velocity is 48 fps. NOTE: At the start, the object is at the zero-reference point of
displacement.
a. Draw the a-t graph. Find the equation of the acceleration as the function of time.
b. Draw the v-t graph. Find the equation of the velocity as the function of time.
C. Draw the s-t graph. Find the equation of the displacement as the function of time.
