Homework Statement
An individual standing at the equator:
a)What is this individuals centripetal acceleration caused by the Earth's rotation?
b)How fast would the Earth need to spin in order for the centripetal acceleration to be equal to g?
T=1 day
radius of Earth = 6.4x10^6 m
Homework Equations
a=v^2/r, v=2pir/T
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)
