One way of lifting a satellite into geosynchronorous orbit is to use the space shuttle to lift it into a circular, low-earth orbit(h=300km) and then use a booster rocket to place the satellite on a hohmann transfer orbit up to a circular geosynchronous orbit. what is the orbital velocity of the satellite while it is still in low-earth orbit? what is the orbital velocity at pericenter, of the appropriate hohmann transfer orbit? what is the orbital velocity at apocenter of the hohmann transfer orbit? how long does it take the satellite to travel from the low-earth orbit to the geosynchronous orbit? 2. Relevant equations v=sqrt(g*m/r) i think Vp=sqrt(U(2/r-1/a) Va=sqrt(U(2/r-1/a) 3. The attempt at a solution i found the orbital velocity of low-earth orbit using v=sqrt(g*m/r) = 7.67km/s i don't know how to find the rest. a little help please?
