AI Thread Summary
To launch a toothpick 12 inches using a 6 Volt lantern battery, magnets, and wire, one suggested creating a strong electromagnet with a metal core and sufficient wire. A "beakman's motor" was attempted but did not succeed in launching the toothpick. The discussion emphasizes the need for a powerful electromagnet to achieve the desired distance. Participants express uncertainty about the exact amount of wire and iron needed for effective movement. Exploring alternative methods and designs is encouraged for successful implementation.

Homework Statement


Make a toothpick move or shoot 12 inches using a 6 Volt lantern battery, magnets, wire, (& anything else necessary)

Homework Equations



The Attempt at a Solution



Made a "beakman's motor" and tried to insert a toothpick in the wire, so it can spin and then launch, but failed, need another solution/ideas to try, using the above materials.

No Help? :cry:
 
you can make a pretty strong electromagnet that will move a toothpick with a bit of metal stuck to it... youl need a core though and a fairly big bit of wire. don't honestly know how much wire/iron youl need to get it to move from 12inches away... just spit-balling

Thread 'Variable mass system : water sprayed into a moving container'

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}...
