Problem: An undiscovered planet many light years from earth has one moon in a periodic orbit. This moon takes 22 days on average to complete one nearly circular revolution around an unnamed planet. If the distance from the center of the moon to the surface of the planet is 2.390 x 105 km and the planet has a radius of 3.350 x 103 km.
Part A: Calculate the moons radial acceleration?
Please show all work and steps to determine the moons radial acceleration.
