Awesome Egg Drop

There is an egg drop competition. If you egg survives, you get points for mass*time. The lowest score gets extra credit. So...Assume you have a helium balloon. The mass of a helium balloon is negative. The time it takes to fall will be close to infinite. Therefore the score will be negative infinity = extra credit. It works, right? :D

You know you're an AP student if...

you think studying is fun.
you constantly find yourself saying "we had homework?"
everything you know about sex, you learned in english class.

If you try to fail, and succeed, which have you done?

How is the mass of a helium balloon negative?

W = FD = mgD = mass * -9.8 * Distance. The balloon is moving up, so distance is positive, and work is positive. Therefore mass must be negative.

You cannot beat my flawed logic :D

Umm... In my world, at least, you cannot have a negative mass :P

And please don't go get all Albert Einstein on me to prove that you can :P

In chessmaster's equation, mass isn't negative, the acceleration is.

Although, you'd have to have a lot of helium to create a bouyant force that would lift the egg up.

Acceleration is negative, work and distance are positive, therefore mass must be negative. I was just trying to get a thread started about random physics arguments(yes I am that nerdy, get over it). Do you think I can get points for creativity.

Well, I think indeed you can. Too bad my friend Lars isn't a member on this site-he would have started arguing and bleating euqations at you, while going off on random tangents.

hello, my name is Lars II, I do better doing that at history or math. That is the one thing I don't like about physics, its a lot harder to argue about it.

Well if you want a good physics argument going on why not argue the following:

What happens if you have an unstoppable ball and an unpassable wall and the ball runs into the wall?

AAAAHHHHHHHH!!!!!!!!!!! An unstoppable/answerable joke!!!!! *Groans, and falls off of chair, convulsing as the bad joke courses through her system*
