When the Moon is directly overhead at sunset, the force by Earth on the Moon, FEM, is essentially at 90° to the force by the Sun on the Moon, FSM, as shown below. Given that FEM = 1.98 ✕ 1020 N and FSM = 4.36 ✕ 1020 N, all other forces on the Moon are negligible, and the mass of the Moon is 7.35 ✕ 1022 kg, determine the magnitude of the Moon's acceleration (in m/s2).
