In Mostar, Bosnia, the ultimate test of a young man’s courage once was to jump off a 400-year-old bridge (now destroyed) into the River Neretva, 23.0 m below the bridge.
(a) How long did the jump last?
(b) How fast was the diver traveling upon impact with the water?
(c) If the speed of sound in air is 340 m/s, how long after the diver took off did a spectator on the bridge hear the splash?
