# Can an Orange Break Through 1/2" Drywall?

• claegreid
In summary, if you throw an orange through a 1/2" sheet of drywall (gypsum board), it will most likely fly apart and be destroyed. If you are trying to do this experiment, be very careful and do not do it at home.f

OK, PF, I have an argument to settle and I need some expert advice.
A friend of mine claims that it is possible to throw an orange through a 1/2" sheet of drywall (gypsum board); several other friends refute his claim. I would like to do the math to prove/disprove the theory, but my line of work doesn't give me a lot of practice with the physics of such dynamic elements.

Question to the forum: how would I go about setting up an equation solve for this problem.

Why don't you just give it a try?

That's the next step. But if I find out how much force is necessary and it is more than a human arm can supply, then I will have to build a cannon of sorts to achieve what man cannot.

1/2" drywall is not very strong. Especially if you freeze the orange first...

Especially if you freeze the orange first...

And don't forget that if a baseball pitcher or a cricket fast bowler did the experiment, the orange would hit the drywall traveling at more than 90 mph.

Perhaps google for the impact properties of drywall. If you can't find them you will have to do the experiment.

Don't try this at home, folks!

Uh, this seems to be outside the conditions of the OP... ? I refer to the word "throw"...

The question becomes one of whether the orange will fly apart from the acceleration or air turbulence before it gets enough momentum to break the drywall.
