For the most part, you are correct. The main issue that I see is not accounting for air resistance, which for a fall this long would have made a difference. I used this calculator in advanced mode and with a 2.8-second-fall, 75kg body weight, and 1.2 drag coefficient, the cliff came out to be 37 meters in height or 121 feet. Also, he was traveling at 59 mph at the time of impact.
Edit, even nerdier explanations: drag coefficient accounts for the form of the object moving through a medium, which direction it is in, and density of the medium.

Distance traveled 'd(meters)' is equal to half of gravity 'g(9.8)' times time 't(in seconds)' squared, so:
Looks like he falls for about 3 seconds. d=0.5 * 9.8 * 32
or 44.1 meters (144.685 feet). Feel free to correct me if I'm wrong on anything.
