He threw the ball 16 ft above his head. I assumed he is six feet tall, so it went a total of 22 ft above the ground. In case you are interested, here is how I did it: The ball is going to start with some unknown velocity (v), go up in the air in a parabolic arc and then come back to the ground. As it passes the point from which he threw it (6 ft) on the way down it will be traveling with the same velocity (v) it started with but in the opposite direction. There are two parts to the path: part a (up and down to his head): height = ya time = ta part b (from his head to the ground): height = yb = 6 time = tb Now we can set up some equations: ya = v^2/(2*g) (g= gravitational constant = 32.2 ft/sec^2) yb = 6 = v*tb + (1/2)*g*tb^2 ta + tb = 2.36 ta = (2*v)/g I threw these in a spreadsheet and solved for v using the Goal Seek function. Final values: v: 31.9 ft/s ta: 1.98 s tb: 0.38 s ya: 15.8 ft Took me about ten minutes to solve. Yes, I am a geek and proud of it.

LOL Jeff, do you mind if I share that on Utefans (aka Cougarboard lite), source anonymous?

But you were correct about it being an extremely nice day. My son and I enjoyed the game; the stadium was a fun place to watch a game. We were low on the sideline next to the endzone with an unobstructed view of Locker's celebration. I've never felt more humiliated than by his egregiously offensive display of poor sportsmanship and taunting. Actually, I thought he was a superb athlete and didn't think he did anything wrong at all. At the time, I assumed a Dawg player has said something offensive, although that would have been surprising because I didn't see any nastiness from either side throughout the game. It was an unfortunate call. But BYU outstatted UW in every offensive and defensive category, and deserved to win. Downtown Seattle last evening was gorgeous. We had a nice meal at Etta's (?), and I returned to the Space Needle for the first time since 1962 when I was 9 years old. Didn't notice any changes, other than a major price increase. Assholes. |

Four years ago I made the mistake of going to the Space Needle with an engineer. He just wanted to walk around it drooling while muttering "of course! Triple reinforced truss!" "Wow, no diagonal elements anywhere!" "Lateral load-bearing systems, naturally!"

That might have been interesting, for about three minutes anyway. Unfortunately, engineers seem to thrive on tedium and I feel your pain. As we were ascending, it occurred to me that earthquake building standards may have evolved in the past 46 years, and I was hoping a 7.0 didn't hit while we were up there. Perhaps you could ask your friend about whether the Needle has been retrofitted, or if that's even needed. Okay, don't.
