Recession of the Moon Careful measurements of the earth-moon separation indicate that our satellite is presently moving away from us at approximately 3.0 cm per year. Neglect any angular momentum that the moon might be transferred from the earth to the moon. Calculate the rate of change (in rad/s per year) of the moon's angular velocity around the earth (consult Appendix E and the astronomical data in Appendix F). Is its angular velocity increasing or decreasing? (Hint: If L = constant, then dL/dt = 0.)
