Math Problem Statement
Trying to determine its depth, a rock climber drops a pebble into a chasm and hears the pebble strike the ground 4.00 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?
(b) What is the percentage of error that would result from assuming the speed of sound is infinite?

Formulas
Equation of motion: d = (1/2) * g * t^2
Speed of sound: t2 = d / vs
Total time equation: t_total = sqrt(2d/g) + d/vs
Percentage Error: (|d_infinity - d_actual| / d_actual) * 100%
