An individual standing at the equator:
a)What is this individuals centripetal acceleration caused by the earths rotation?
b)How fast would the earth need to spin in order for the centripetal acceleration to be equal to g?
radius of earth = 6.4x10^6 m
The Attempt at a Solution
We need to convert the period from day to seconds and then plug in the information.
a=4pi^2r/T^2 = 4pi^2(6.4x10^6)/(1x60x60x60)
