Compute the period of the planets rotation

Reference no: EM13487305

A newly discovered planet has a mean radius of 2020 km. A vehicle on the planet\'s surface is moving in the same direction as the planet\'s rotation, and its speedometer reads 121 km/h. If the angular velocity of the vehicle about the planet\'s center is 1.53 times as large as the angular velocity of the planet, what is the period of the planet\'s rotation?

_____Hours

If the vehicle reverses direction, how fast must it travel (as measured by the speedometer) to have an angular velocity that is equal and opposite to the planet\'s?

______Km/h
