1. In the time it takes us to travel from the orbit around Kerbin to the Mun, through what angle does the Mun move along its orbit? Enter your answer in degrees, to two significant figures.

2. If h=2.010⁵ m, rKerbin=6.010⁵, rMun=2.010⁵, and RMun=1.210⁷ m, what is the numerical value of a?

Enter your answer in Mm (millions of metres) to 2 sig fig. Do not write the units.

3. To calculate the period of the orbit, we need to know the mass of Kerbin.

a. True

b. False
