You could have calculated it directly from this..
S = 1/2 A T**2 A = 32.2 ft/sec/sec (9.8 m/sec/sec)
S is distance.. 1/2 x 32 x (3.8)**2
Since I am lazy, I will call it 4 seconds...
1/2 x 32 x 4**2 = 16 * 16 = 256 feet high, so your 230 is probably right. You just did it the hard way.
Of course, this assumes she didn't slow down due to wind resistance....
Also, V = AT so she was moving at V = 32 * 4 = 128 feet per second, or 87 mph, when she hit the ground.
I am available for all forms of math, science, physics, and engineering solutions
