So I want to prove my friend wrong when he says he can throw a pineapple through our living room floor and I don't really know how I would calculate that.(adsbygoogle = window.adsbygoogle || []).push({});

I've determined our floor is composed of different layers, looking something like this:

------ Parquet flooring [~1 cm] (800 kg/m3)

------ Plywood [~1.3 cm] (700kg/m3)

--|---

--|--- Insulation [~15.2 cm] (500kg/m3)

--|---

--|---

------ Drywall [~0.6 cm] (800kg/m3)

I figure the variables needed to figure this out would be the distance the pineapple would have to go through (the thickness of each layer), the density of each layer, the mass of the pineapple (about 1 kg), and how much force a male can possible throw a pineapple with so I can compare.

I'm going to assume he won't hit any pipes or wires and that the pineapple won't smash and crack open by pressure just to simplify the question.

I know what information I have, and I know what I'm looking for (force)...I just don't know how to get there. It's been too long since I've taken a physics class. I think I would have to do a seperate calculation for each layer. I think it has something to do with the force exerted by the layer being greater then the force exerted by the pineapple so the pineapple would go through it and it has a positive net force.

I need help though. I'm stuck! I don't know any equations that would help me figure this out. I just know using common sense, it won't work lol. :shy:
