A planet has mass Mplanet = 4.46e24 Kg and a radius Rplanet = 5900 Km Some space explorer lands on the equator of this planet and he weighs 161lbs, whereas he weight 185lbs on Earth. He journeys over to the North pole and he finds himself weight only 95% of what he did at the equator. Now the question is how long does it take the planet to make one complete revolution. I am completely lost. how does weight of person and revolution of planet related??
