## Homework Statement

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?

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)
