When you drop a 0.35 kg apple, Earth exerts a force on it that accelerates it at 9.8 m/s^2 toward the earths surface. According to Newton’s third law, the apple must exert an equal but opposite force on Earth. If the mass of the earth is 5.98x10^24 kg, what is the magnitude of the earth’s acceleration toward the apple? Answer in units of m/s^2.
