1. The problem statement, all variables and given/known data 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. 2. Relevant 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 3. 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?
