Draw the Free Body Diagram (with the orbit) of a satellite orbiting the Earth in a circular orbit on the board. Write the expression for the velocity of the satellite as a function of F. 

For full credit: 

1. *circular* orbit is drawn, and satellite is drawn with a dot or a box labeled m

2. There is the force labeled Fg pointing toward Earth

v = √(Fr/m)

Does sound travel faster in Space or near the surface of the Earth? Explain. 

Answer: "faster" near the surface of the Earth.

Sound does not travel at all in Space: because Space is a vacuum and no air molecules can collide with each other.

What is the chemical equation for the mixing of liquid hydrogen and liquid oxygen as propulsion?

2H2(l) + O2(l) -> 2H2O(g)

Need all states correct for full credit.

Draw a Free Body Diagram of an aircraft mass m, not neglecting air resistance. 

Needs to include: lift pointing up, mg pointing down, thrust pointing forward, drag pointing backwards.

A rocket is launched from the Earth at 25,500mph straight up from Earth's surface. Assume g = 9.8m/s2, Earth's radius is 20,900,000 feet, and the mass of the Earth is 5.97 × 1024 kg. Assume no air resistance. How high will the rocket go?

1 mile = 5280 feet = 1.609 kilometers

No solution. 25,500mph is faster than the escape velocity, so it will not return.

What were the last names all of the of the astronaut(s) who flew on the mission that planted the first American flag on the huge gray rock orbiting the Earth?

Armstrong, Collins, Aldrin
