Homework Help: Radial acceleration

  1. Oct 30, 2004 #1
    I need to calculate the radial acceleration of earth @ the equator

    a=v^2/r
    a= [1041m/s)^2]/6378m
    a= 169.9 m/s^2

    is this correct?

    I think the radius of the Earth is a tad larger than 6.4 km.
    How did you get the v? The distance traveled in a day is the circumference of the equator.
