if the command module is 60 miles above the surface of the moon it wants me to calculate the speed of the module adn the time it takes to complete one revolutionaround the mooon?
givens
mass moon = 7.35 * 10 to the 22 power
radius moon = 1.74 * 10 to the 6 power
altitude above the surface of the moon = 60 miles
converted the 60 miles to meters which was 96540 m
Ro = Rm + h
Ro = 1.74E6 + 96540
Ro = 1.74E22
Vcm is the command module
Vcm^2 = G * Mm/ro
Vcm^2 = 6.673E-11 * 7.35E22/1.74E22
Vcm = 1.679 meters/sec
and not sure if this is right and don't know what to use to figure out the time it took to make 1 revolution
thanks
