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

Homework Statement Homework Equations 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...

Homework Statement Homework EquationsThe Attempt at a Solution The answer is different though,

thanks for everything, it was a confusing one

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...

but it's not accepting it as my answer, it's looking for a height

actually nvm forgot to square it, i got 0

i got -6.26*10^7

ξ=(sqrt(2(6.67*10-11 * 5.98*1024))^2/2 - (6.67*10-11 * 5.98*1024)/6.371*106

i meant V initial

I used the ξ equation and plugged the escape velocity in vf2

got 99716437393501.805

so i did sqrt(2GM/R) and plugged into v12 and got ξ = 63816956.64

It never stops, infinity? but the question is looking for a specific number

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
