No, not the ferrous metal ones that magnets stick to.
My question pertains to what would happen if you shot a neodymium magnet out of a shotgun. I've see a video where they do it and they stick together but what about their effects on electronics? If you hit it and they didn't penetrate...
Problem is the solution with the log function is giving me ansers of several thousand years for a flight time
This is where I get K, it's everything but the V squared term and divided by mass.
Edit: hold on, it could be my drag co-efficient is f'ed up.
Cool, so I've solved for V:
V= 1/(KT+1/Vi)
Wolfram integrates it as
Log(KTVi+1)/K=X
That doesn't seem right,
If I simply integrate KT+1/Vi with respect to X (because 1/v is dT/dX) I get
KTX+X/VI=T
Which becomes
X/(Vi-KXVi)=T
So this gives me:
1/kv+vi=T correct?
From here I changed the V to dx/dt but since it is 1/v it becomes
(1/k)*dt/dx+Vi=T
Multiplying by dx I then get
(1/k)dt+Vidx=Tdx
Integrating yields
T/k +ViX=T*X (accounting initial time and distance as zero)
But that just seems wrong...

Okay I'm working on making a ballistics calculator and I need to know how to integrate this.
To get velocity, and ultimately to get time of flight. So that I can use that to determine drop with an angle of 0.
actually I re wrote the thing in an easier form but it gets messy if you just use separation of variables
dv/dt=-fV^2-9.8
I can't remember how to do this using ODE, any help?
http://latex.codecogs.com/gif.latex?(d^2Y)/(dTdY)=%20-c(dY/dT)-9.8(dT/dY)
basically how do you integrate dy/dt with respect to y, I know dy/dt integrated with respect to t is simply Y, but the other I have no idea.
