When the moon is directly overhead at sunset, the gravitational force on the Moon due to the Earth, F⃗ EM , is perpendicular to the gravitational force on the Moon due to the Sun, F⃗ SM . These two forces have magnitudes FEM=1.98×1020 N and FSM=4.36×1020 N . Assume that all other forces are negligible. The mass of the Moon is m=7.35×1022 kg . Write an expression for the magnitude of the acceleration of the Moon.
