Egg Drop Project and Kinetic Energy

AI Thread Summary
The Egg Drop project requires a design that protects an egg from a fall while adhering to strict size and weight limits. The goal is to minimize the transfer of kinetic energy to the egg, ideally by extending the fall distance. A proposed solution involves using multiple layers of paper to create a cushioning effect, with considerations for securing the layers effectively. Suggestions include exploring various materials and techniques, with an emphasis on creative designs that can absorb impact. Researching online for egg drop project ideas can provide additional inspiration and methods.

Homework Statement


[/B]
Our teacher has given us the weekend to go and work on the Egg Drop project. He's restricted us to 20g total mass and 6cm * 6cm * 30cm in size. Food, foam, bubble wrap is prohibited. Parachutes can be added but can not make it exceed 12cm * 12 cm * 30cm.

So that's what was given. I'm curious if there's any well known recommended way to do this. I understand the main concept is to make Kinetic energy be transferred to the egg slowly over a longer distance (rather than the regular one point on the ground). Any suggestions?

Homework Equations



No real equations to plug in here, just more application of basic ideas of energy and motion.

The Attempt at a Solution



My main idea of doing it was to have multiple layers of paper the egg can fall through, the main problem would likely be securing the layers together. A piece of paper is approximately 4.5g, so the limit is basically 4 pieces of paper to be safe. I'd think maybe one piece for a tubing to secure the egg in, then do layers of paper on the way down, with tape securing them?

Any other suggestions of methods or materials to use?

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
