Homework Help: Linear/Angular Velocity and Acceleration

  1. Feb 6, 2010 #1
    1. The problem statement, all variables and given/known data

    A sphere of radius r0 is rotating about an axis through its geometric center with fixed angular velocity Ω0. Measuring latitude and longitude as is done for the Earth, what is the angular velocity of a point at Θ0 degrees North and Φ0 degrees East.
    What is the linear velocity?
    What is the angular acceleration?
    What is the linear acceleration?

    2. Relevant equations

    I don't understand the relationships between angular and linear or how to begin to set this one up.

    can you negate phi since your distance from the center of the sphere doesn't change at all?

    Can anyone offer any help on this?
