What is your team up to at your hotel?

I'll let all you bright students calculate the damage that can be done by solid objects dropped from great heights. The Marquis was filled with FIRST students and volunteers.

Assuming that the bouncyball weighs a tenth of a pound (or so, .05kg to be precise), dropped from the very top of the atrium to the very bottom...

67.13 Newtons.

That is (assuming I remember correctly) four times the force of a golfball dropped from one meter.

So yeah. It'd hurt. Because golf balls dropped from one meter hurt. But this would hurt more.

EDIT: Whoops! For some reason 40 * 4 = 60 in my brain

but basically it's a lot of force. And would hurt. Even if you take off the 2m or so from the height (assuming it hits a 2m tall person on top of the head) it's still going to hurt.

edit:

that's 2.7m/s, or .1mph.


edit (yes again):

It will take 52 seconds to hit the ground, too.

edit (whee):

I did some more math

here's the full thing:
"A bouncyball dropped from the top of the atrium at the Mariott Marquis, assuming it weighs .05kg, Will hit the ground with a force of 67.13N. The ball falls at a speed of 2.78m/s and will take 52 seconds to hit the ground. Assuming optimal conditions, that's going to be a 132m rebound at 90% effeciency. The ball, dropped from the 47th floor, will get back up to the 42nd floor."
