**Scott**, Wednesday, September 12, 2012 at 7:20pmstone time (T) plus splash time (t) equals watch time minus reaction time

T + t = 3.65 - .25 __ t = 3.4 - T

d = .5 * g * T^2 __ g = 9.8 m/s^2

also, d = 340 * t __ d = 340(3.4 - T)

4.9 T^2 = 1156 - 340 T

4.9 T^2 + 340 T - 1156 = 0

use quadratic formula to find T, then plug in to find the depth
