A stone is thrown downward into a well with an initial speed of 5.00 m/s. The sound of splash is heard 1.50 s later. Find the depth of the well if the air temperature is 15.0 ˚C?
You know the total time.
disance=vo*timedown+1/2 g * timedown^2
NOw, on the wa7 up..
set them equal, solve for time down, use the quadratic equation. From that, go to the distance equation and solve for distance.
