Question 1: Emily challenges her husband, David, to catch a $1 bill as follows. She holds the bill vertically, 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? Yes or No Explain your reasoning. Question 2: In Bosnia, the ultimate test of a young man's courage used to be to jump off a 400-year-old bridge (destroyed in 1993; rebuilt in 2004) into the River Neretva, 23 m below the bridge. (a) How long did the jump last? ___________s (b) How fast was the jumper traveling upon impact with the river? _____________m/s (c) If the speed of sound in air is 340 m/s, how long after the jumper took off did a spectator on the bridge hear the splash? __________________s
