An undiscovered planet, many lightyears from Earth, has one moonin a periodic orbit. This moon takes 1960 Ý 103 seconds (about 23days) on average to complete one nearly circular revolution aroundthe unnamed planet. If the distance from the center of the moon tothe surface of the planet is 285.0 Ý 106 m and the planet has aradius of 3.50 Ý 106 m, calculate the moon's radialacceleration.
