When the moon is directly overhead at sunset, the gravitational force on the Moon due to the Earth, F EM, is perpendicular to the gravitational force on the Moon due to the Sun, F SM. These two forces have magnitudes F EM=1.981020 N and F SM=4.361020 N. Assume that all other forces are negligible. The mass of the Moon is m=7.351022 kg. What is an expression for the magnitude of the acceleration of the Moon? What is the acceleration of the Moon in m/s^2?
