1. The problem statement, all variables and given/known data In Bosnia, the ultimate test of a young man's courage used to be to jump off a 400 year old bridge (now destroyed) into the River Neretva, 23 m below the bridge. (a) How long did the jump last? (b) How fast was the jumper traveling upon impact with the river? (c) If the speed of sound in air is 341 m/s, how long after the jumper took off did a spectator on the bridge hear the splash? 2. Relevant equations a. and b. change in Y=Voy t - .5 gt2 3. The attempt at a solution a. v=21.23 m/s b. t=2.167s c. Vy=Voy - gt 341 m/s =21.23 m/s - 9.8 m/s2 t t=-32.63s I know that time cannot be negative, but I have tried the inverse of this number also, and I am still getting it wrong. Am I even using the correct equation?
