The earth has a radius of 6380 km and turns around once on its axis in 24 h.

Part A

What is the radial acceleration of an object at the earth’s equator? Give your answer in m/s².

Part B

What is the radial acceleration of an object at the earth’s equator? Give your answer as a fraction of g.

Part C

If arad at the equator is greater than g , objects would fly off the earth’s surface and into space. What would the period of the earth’s rotation have to be for this to occur?
