Centripetal acceleration

  1. Feb 22, 2009 #1
    1. The problem statement, all variables and given/known data

    Observing an orbit of Earth around the sun, calculate the centripetal acceleration of Earth.

    2. Relevant equations

    Fc = mv^2/R
    Only the distance aka radius was provided, to be 1.496x10^11m.

    3. The attempt at a solution

    No mass of earth provided.

    Welcome to Physics Forums mrmoar.

    HINT: Can you find a relationship between the centripetal acceleration and the period of rotation?

    okay thanks for the hint but i didnt really get the answer. taking the formula

    Acc = radius x omega^2
    omega = 2pie (1orbit) / time

    i took time to be 365.25 x 24 x 60 x 60 to get s.

    My results were wrong :(

    Perhaps if you showed us your calculations, we could point out where you're going wrong.
