An early major objection to the idea that Earth is spinning on its axis was that Earth would turn so fast at the equator that people would be thrown into space. Given : rearth = 6.37 × 106 m , mearth = 5.98 × 1024 kg , rmoon = 1.74 × 106 m , and g = 9.8 m/s 2 . Show the error in this logic by calculating the speed of a 105 kg person at the equator. Answer in units of m/s. 005 (part 2 of 3) 10.0 points Find centripetal force on the person. Answer in units of N. 006 (part 3 of 3) 10.0 points Find the weight of the person. Answer in units of N.
