Homework Statement


the earths gravitational field is sufficiently strong enough to keep us on it- even though we are travelling in a circle on its surface. But how fast would we be spinning before we started to fall off? What about at latitude 53 (UK)? and how long would a day be?


Homework Equations



w=theta/time
w=v/r

The Attempt at a Solution


i got 59 minutes for the day using 2pi/1.75x10-3

Is that your result for the equator or the UK latitude?

Either way, it doesn't look right to me. Can you show your work?
