Homework Statement
The space shuttle is in a 300 km-high circular orbit. It needs to reach a 610 km-high circular orbit to catch the Hubble Space Telescope for repairs. The shuttle's mass is 7.00×10^4 kg.
Homework Equations
½(-G(M-earth)(M-telescope))(1/r2 –1/r1)
G=6.67*10^6
Mass of earth=5.98*10^24
Mass of telescope= 7.0*10^4 kg
Radius of earth= 6.98*10^6 m
The Attempt at a Solution
What I did was plug in the numbers to the equation. For r2 I added the radius of Earth + the height needed to be attained (610km). For r1 I added the radius of Earth plus the original height (300km). I keep getting 8.4*10^10 which is the incorrect answer. What am I doing wrong?
