1.Carlos becomes an Aerospace Engineer for NASA and needs to send a 5,000 kg rocket containing astronauts and supplies to the International Space Station (ISS) which orbits Earth at an altitude of 254 miles (408.8 km). What speed must Carlos give the rocket so that it orbits Earth at that altitude?
2.Jennifer joins NASA as an astronaut, but instead of being sent to somewhere cool like Mars she is stuck in a 12,000 kg spacecraft orbiting Venus. If Jennifer's spacecraft is orbiting Venus with a speed of 9,000 m/s, what is the radius of Jennifer's orbit? [Hint: you're looking for "r"]
B.Violet also joins NASA as an astronaut, and does get to go to Mars. What is the acceleration due to gravity that Violet feels when she gets there? If Violet throws a Mars rock straight up with a speed of 25 m/s, how high will it go?

A rocket carrying a new 945-kg satellite into orbit misfires and places the satellite in an orbit with an altitude of 175 km, well below its operational altitude in low-Earth orbit. (a) What would be the height of the satellite's orbit if its total energy were 450 MJ greater? km (b) What would be the difference in the system's kinetic energy? (Include the sign of the value in your answer.) Mj (c) What would be the difference in the system's...
