Homework Help: Linear velocity

  1. Apr 9, 2015 #1
    1. The problem statement, all variables and given/known data
    Find the linear (or tangential) velocity of a point on the Earth's equator in the frame of reference about a stationary rotational axis as it spins over the course of one day.

    2. Relevant equations

    3. The attempt at a solution
    I do not understand what the frame of reference is?? If a frame of reference isn't given, how do i find the linear velocity?

    It means taking the earth's centre as the origin of a non-rotating frame.
