Where is Mark?

He was sighted, still in Atlanta, dancing (what a surprise!) late Saturday night (might have even been Sunday morning ) so may need to tweak the time frame.

I can confirm Mark's spoting at the afterparty around 9pm on Saturday night.

I saw Mark at an after-after party Saturday night. He mentioned something about loading up the truck and getting an early start on the Golden Ball Relay.

So the average mass moved during the trip is 26,100 pounds (Mark plus the Red Bull). Given the Atlanta-San Jose distance, it would take 336 billion ft-lbs of energy to get Mark and the Red Bull home. Mark's observed velocity during the competition is about 60 ft/sec (anyone that has watched Mark as MC during a match can attest to this). At this velocity, it should take Mark about 60 hours to run from Atlanta to San Jose, pulling a trailer full of Red Bull (which he is consuming as he goes). With 1 HP = 550 ft-lb/sec, that would mean he is putting out about 2831 horsepower during his little jog. Yeah, that seems about right.

Anyone else see the conceptual error here?

Force required to move an object is only equal to the object's weight if it's going up. Power to move a trailer carrying a 13 ton payload at 60 ft/sec (about 40 mph) roughly horizontally is certainly much less that 2831 HP.

But since the AP story indicates that only the trailer was removed and the truck was left behind, we have to remember that Mark is dragging the trailer full of Red Bull with him. Although Mark is strong, he is not quite super-human, so I considered that he is pulling the trailer with the front skid down to support some of the weight. So the trailer is not just a free-rolling system on a horizontal plane, but has considerable friction to overcome as the skids scrape along the ground. Without specific CoF data from the trailer/ground interactions, the worst case is assumed (ie. pure vertical movement) to provide the maximum bounding condition for the problem.

Besides, have you EVER seen Mark do anything that did not involve a significant change in altitude?!?!

Silly me! I assumed he'd take the path of least resistance to get to San Jose.

Relying on a deeper understanding of Mark's penchant for expending more energy than the task requires, Dave correctly reasoned that he would elevate the load of bull significantly before translating home.

I stand corrected.

Mark was on the United flight from Atlanta to San Francisco that left early Sunday morning. I followed him as far as I could, but I did not see his destination from there.

Wow, he got from the after-party at 9 pm to San Jose and back to Atlanta in time for a sunday morning flight? That's impressive, I think we need to adjust his estimated velocity!

There was a young lady named Bright,
Whose speed was much faster than light;
She set out one day
In a relative way,
And returned on the previous night!

(ca. 1950s, anthologized by Bennett Cerf)

Fueled by 4 oz/sec of Red Bull, Mark might have a chance to catch Ms. Bright!

I think there is a lot of conjecture in this post. I definitely saw him on the Einstein field congratulating the Champions and the Chairman's winners. I think in their enthusiasm, Thunder Chickens packed him in the crate with their robot. I am guessing he is somewhere in Ohio at the moment.

However, Big Mike was down there hugging Paul again and Mark could have been caught in the fallout. Having been mistaken for blue confetti, he could have been swept up into a big pile and is now in an Altanta landfill.

he rode on the same plan as my team. before the flight he walked up to us and talked for some time about math and physics (like he always does). he had one bag. i doubt he could have checked that many pounds of redbull. he sat next to our driver. i noticed that he walked up and down the isles several times for some reason (not going to the restroom. i'm talking, he went behind the last row and came back to the first row). could have been because of the mass quantity of redbull consumed.

Mark has hidden stashes every where. I asked him last year what they tasted like and he told me (sorry I think it might be bad to post comment here). He then produced a can for me to try. Next day after 4 Red Bull I was almost at the same speed as Mark. I also found out that a guy my age should not start by consuming 4 cans.

By the way Mark is probably kicking that trailer ahead of him. That way the cans are closer to get with less effort. This allows more energy to be used positively. It's all in the math!
