Hey, well the assignment is over now, the correct answer was (Fe*R/B^2*l^2)(1-e^(-b^2*l^2*t/Rm) My final attempt was Fe/m - e^(B^2*l^2*t/Rm) I still got an 88 on the assignment, so its not the worst, thanks for the help though

Would the answer to that be v(t) = β/(1 + \alphat)?

Thanks for the reply, i was way too tired yesterday and not thinking very well... And i have some, but i really struggle with them (been awhile since i took calculus, and i only took the first half). If Fe is on one side, is the next step to evaluate m(dv/dt) from vo to v, and since it is...
