## Homework Statement

What would Earth's rotation period have to be for objects on the equator to have a centripetal acceleration equal to 9.8 m/s^2?

____ min

## Homework Equations

Centripetal acceleration is equal to velocity * (2PI/T),

where T is the period in seconds.

## The Attempt at a Solution

I set centripetal acceleration equal to 9.8m/s^2 and solved for T. Then I took T and divided it by 60 so I could get the answer in minutes. I came out with 4.97 min which Webassign says is incorrect. Any ideas?
