ok, so I know E= chg flux/chg in time

chg flux = Bl(chg x)

but how do i get a time?

x(t) = x_0+v_0*t+.5gt^2.

x_0 = v_0 = 0

x(t) = .5gt^2 solved for t becomes:

t=sqrt(2*x(t)/g) where x(t) = 9.53 and g = 9.8ms^-2

That doesn't seem to be working, anymore ideas? Am i even going about this problem the right way?

Absolute value of emf, [tex] v = d\phi \dt = 14.2 *B dx/dt[/tex]

Induced emf when the pole hit the ground is obtaind by substituting the velocity of the pole when it hits the ground which = sqrt (2gh) where h=9.53m

Note:

Lately I have not been able to view LaTex Formula. I hope the above shows ok in your browser.
