If the rotation of a planet of radius 3.41 106 m and free-fall acceleration 8.71 m/s2 increased to the point that the cen- tripetal acceleration was equal to the gravita- tional acceleration at the equator, what would be the tangential speed of a person standing at the equator?

How long would a day be in this case?
