A student with mass 55 kg jumps off a high diving board. Part A Using 6.0×1024 kg for the mass of the earth, what is the acceleration of the earth toward her as she accelerates toward the earth with an acceleration of 9.8 m/s2 ? Assume that the net force on the earth is the force of gravity she exerts on it. Express your answer in meters per second squared. |a| = m/s2
