A 4.98 × 1022 kg moon orbits about a 3.82 × 1027 kg planet. The radius of the moon's orbit is 1.61 × 108m.
The moon travels in a nearly circular path at approximately a constant speed.
What is the acceleration of the moon toward the planet in meters per second squared?
(Assume Gravitational force of planet onto moon is only force acting on it)
