When it orbited the moon, the apollo 11 spacecraft's mass was 10400 kg, its period was 133 min, and its mean distance from the moon's center was 1.99345 × 106 m. assume its orbit was circular and the moon to be a uniform sphere of mass 7.36 × 1022 kg. given the gravitational constant g is 6.67259 × 10−11 n m2 /kg2 , calculate the orbital speed of the spacecraft. answer in units of m/s?
