Ohhh wait, conservation of energy applies, right? Ek1 + Eg1 = Ek2 + Eg2 just plug v2 = 7404.5 m/s in

Would that be Ek = ΔEg 1/2mv^2 = -GMm/r2 - (-GMm/r1) solve for v, then add it to 7404.5 m/s?

Homework Statement How fast must a satellite leave Earth's surface to reach an orbit with an altitude of 895 km? Homework Equations v = √GM/r The Attempt at a Solution G = 6.67 x 10^-11 M = 5.98 x 10^24 r = (6.38 x 10^6) + (8.95 x 10^5) = 7.275 x 10^6 v = √(6.67 x...

I believe.. 5 cm to his left? Hopefully I'm understanding this now.

Aye, okay. x = 14(0) + 80 (36) / 14 + 80 x = 31 cm Thanks Doc Al.

How do I do that? :redface:
