Trying to determine its depth, a rock climber drops a pebble into a chasm and hears the pebble strike the ground 3.74 s later. (A) If the speed of sound in the air is 343 m/s at the rock climbers location, what is the depth of the chasm? (B) What is the percentage of error that would result from assuming the speed of sound is infinite ?
