Would that help? We haven't learned anything about that, and it's nowhere in the textbook, not sure if I'm allowed to use things from outside the curriculum

at point C:
i2 - i3 - i4
i2 = i3 + i4[/B]
The Attempt at a Solution
I labeled all the currents going through each resistor in the picture[/B]
for loop ABC:
2000i1 = 3000i2 + 4000i3
for loop BDC:
3000i5 = 2000i4 + 4000i3
at point C:
i2 - i3 - i4
i2...
The hint for the problem was " Kinetic energy is converted into gravitational potential energy. Don't forget to subtract the radius of the Earth from your final distance to determine the final distance above the surface of the earth."
I thought I was doing it right, as my original answer did...
would have
(1/2)(11400^2)-((6.67*10^-11)(5.98*10^24))/(6.371*10^6)=(1/2)vf^2
which would make vf = 2178.762
but I don't see where I can get the h variable from if i set potential final energy to zero
