Homework Help: Gravitational fields

  1. Oct 5, 2011 #1
    1. The problem statement, all variables and given/known data
    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?

    2. Relevant equations


    3. 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?
