A disgruntled man angrily throws a 5 kg ball off of the roof of a 50m tall building with an initial velocity of 12 m/s at an angle of 32 degrees above the horizon. A piece of paper is taped to the side of the ball before it is thrown. It reads: "There are 4 homeomorphically irreducible trees of size n=8. Cayley's Formula cannot be used to find the number of possible homeomorphically irreducible graphs of size n=16."

Does the ball impact the ground?

hint: There is a correct answer.

no, it floats away in space

So, you can't stop the trees from turning gay?

And you think even a gay tree would let a ball touch the ground?

No.

Is the man blind?

The whole time?

Is the building on a treadmill?

Where do I use the AR15.com constant (87)?

I dont give a fuck what is written on the paper. If you throw a ball off a roof it will hit the ground. Eventually one day that shit will touch the earth.

Does the ball impact the ground?

Yes, because gravity and stuff.

It lands in a tree and is stuck there.
It does not hit the ground.

The paper may hit the ground first, but the ball will eventually touch the ground?

12 m/s is slow, say compared to a M855 projectile. A bullet fired at the same angle will hit the ground so will the cube

Nice try. Some of the same words, not even close to the same problem.

I got 39.8 meters from the base of the building but that seems short so maybe I plugged in the wrong numbers.

Using:
range = vcos O/g(vsin O + sqrt(v^2sin^2 O + 2gy)), where O = theta

The ball won't hit the ground if there is something in the way, like another building

Is there a treadmill somehow involved---even peripherally? It does tend to affect the math.

Posted: 3/15/2015 3:54:08 PM EDT

[#41]

Insufficient information.

Assumptions:
This takes places on the surface of Earth, with normal Earth gravity and atmosphere applying.
The ball is more dense than the medium above the ground.
The ball is thrown in to empty space with nothing between it and the ground (including the piece of paper).

Probably more. . .

The ball will never touch the ground, but the strong nuclear force that the ball's atoms exert upon the ground will affect it.

Could perhaps two african swallows snatch it out of the air by the note and carry it to Camelot? In that case it doesn't hit the ground. Although that is the heaviest coconut I've heard of.

I hear everything in China is upside down. They do live on the other side of the earth, and according to everyone except that Saudi scholar, the earth is round-ish.

If he is in china, I think it would fall into the sky. Which is what holds up the stars.

I guess it would hit a star?

Am I right?
