One way of lifting a satellite into geosynchronous orbit is to use the space shuttle to lift it into a circular, low Earth orbit (w/ h = 300 km above the Earth's surface), and then use a booster rocket to place the satellite on a Hohmann transfer orbit up to a circular geosynchronous orbit.
a) What is the orbital velocity of the satellite while it is still in low Earth orbit?
b) What is the orbital velocity at pericenter of the appropriate Hohmann transfer orbit?
c) What is the orbital velocity at apocenter of the Hohmann transfer orbit?
d) How long does it take the satellite to travel from the low-Earth orbit to the geosynchronous orbit?

Sasha has just gotten a new job in a nearby city. after comparison shopping, she found that renting a nice two-bedroom apartment would cost around $800 per month. her utilities would cost about $150 per month. sasha has enough money saved for a down payment, and she found that she can buy a three-bedroom house or condo with a mortgage payment of $1,000 per month, including taxes and homeowner's insurance. her utilities would cost about $200 per month. what is the advantage of buying the house over renting the apartment?
