Let's approximate the Earth as a uniform solid sphere with mass M = 5.972 x 1024 kg and radius R = 6371 km. We see it rotating from above in the picture below with initial angular speed wo that corresponds to a 24-hour day. For some reason, the moon (nonrotating) with mass m = 7.348 1022 kg is headed toward the equator at an angle from the tangent at its strike location. What must be the velocity of the moon so the total angular momentum of the Earth and moon is zero? W The picture is 2d; the velocity of the moon is in the plane of the picture Let's approximate the Earth as a uniform solid sphere with mass M = 5.972 x 1024 kg and radius R = 6371 km.
