In Bosnia, the ultimate test of a young nuns 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? (b) How fan was the jumper traveling upon impact with the river? (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?
During a thunderstorm, a frightened child is soothed by learning to estimate the distance to a lightning strike by counting the time between seeing the lightning and hearing the thunder (Fig. P2.25). The speed vs of sound in air depends on the air temperature, but assume the value is 343 m/s. The speed of light c is 3.00 108 m/s. a. A child sees the lightning and then counts to eight slowly before hearing the thunder. Assume the light travel time is negligible. Estimate the distance to the lightning strike. b. Using your estimate in part (a), find the light travel time. Is it fair to neglect the light travel time? c. Think about how time was measured in this problem. Is it fair to neglect the difference between the speed of sound in cold air (vs at 0C = 331.4 m/s) and the speed of sound in very warm air (vs at 40C = 355.4 m/s)?
A soccer player kicks a rock horizontally off a 40.0-m-high cliff into a pool of water. If the player hears the sound of the splash 3.00 s later, what was the initial speed given to the rock? Assume the speed of sound in air is 343 m/s.
Bats sense objects in the dark by echolocation, in which they emit very short pulses of sound and then listen for their echoes off the objects. A bat is flying directly toward a wall 50 m away when it emits a pulse. 0.28 s later it receives the pulse. What is the bat’s speed?
Rachel watches a thunderstorm from her window. She sees a flash of lightning bolt and begins counting the seconds until she hears a clap of thunder 10.0 ??????? later. Assume the speed of sound in air is 340 ?⁄? and the light was seen instantaneously. How far away was the lightning?
Sound produced by a thunderstorm is heard 10 s after the lightning is seen. Calculate the approximate distance of the thunder cloud. (Given speed of sound = 340 m/s)
A boy on a hill A fires a gun. The other boy on hill B hears the sound after 4 s. If the speed of sound is 330 m s-1, find the distance between the two hills.
During a thunderstorm, 5.0 s elapses between observing a lightning flash and hearing the resulting thunder. Approximately how far away in kilometers and miles was the lightning flash? (Assume the speed of sound is 344 m/s.)
An enormous thunderstorm covers Dallas-Ft. Worth. Your best friend Clark is a storm chaser and heads to the center of the storm to take some readings while you stay dry at home. While Clark is at the center of the storm, he sees and hears lightning strike a tree that is 185 m from where he is standing. You are 134 km from the tree. How long does it take for the sound to reach Clark? Assume the speed of sound is 343 m/s. How long does it take for the light to reach you?
Trying to determine its depth, a rock climber drops a pebble into a chasm and hears the pebble strike the ground 3.46 s later.(a) If the speed of sound in air is 343 m/s at the rock climber's location, what is the depth of the chasm? ?m (b) What is the percentage of error that would result from assuming the speed of sound is infinite? ?%
Sound travels at 1530 m/s in sea water. A signal sent down from a ship is reflected at the bottom of the ocean and returns 1.35 s later. Assuming the speed of sound was not affected by changes in the water, how deep was the ocean at that point?
A bat uses echolocation to detect prey as small as about 1 wavelength of the sound of a bat call. Assume a bat produces a sound with a frequency of 60.9 kHz, and the speed of sound in air is 339 m/s. What is the length in mm of the smallest prey the bat can detect?
