On july 19, 1969, apollo 11's revolution around the moon was adjusted to an average orbit of 111 km. the radius of the moon is 1785 km, and the mass of the moon is 7.3 â 1022 kg. (a) how many minutes did apollo 11 take to orbit the moon once? incorrect: your answer is incorrect. min (b) at what velocity did apollo 11 orbit the moon?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
