Statement of a problem № 41543


The earth has a radius of 6380 km and turns around once 011 its axis in 24 h. (a) What is the radial acceleration of an object at the earth’s equator? Give your answer in m/s2, and as a fraction of g. (b) If a red at the equator is greater than g, objects would fly off the earth’s surface and into space. (We will see the reason for this in Chapter 5.) What would the period of the earth’s rotation have to be for this to occur?
