Could you explain this a little more? Will it just approach the terminal velocity in limit? Because there must me a point at which the acceleration due to the induced force is equal to the acceleration of gravity, so the net acceleration is zero, so it must be moving at some constant speed, even...
Okay, I overlooked that. Thanks.
I think I may have figured something out. Would you tell me if mathematically this is legal and this process makes sense to you in the context of this problem?
I took the bottom equation from my previous reply and substituted ##y=vt##. Then, I know that the...
Using the differential equation
## \frac{dv}{dt}=g-\gamma v##
I used separation of variables and integrated from 0 to ##t## to get
## v-v_{o}=(g-\gamma v)t ## and knowing ##v_{o}=0## i got the equation
##\frac{dy}{dt}=(g-\gamma v)t## so separating variables and integrating again I get that...
I calculated the current by ## I=\frac{emf}{R} ## and the resistance by ##R=\frac{\rho_{e} (4l)}{A}##
I then calculated the emf by taking the negative time derivative of the flux. Using the emf and the resistance I got ##I##.
My professor claims this problem will be independent of mass.
