Homework Help: Dynamics - Need help understanding Coriolis acceleration

  1. Apr 13, 2016 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    Coriolis Accel = 2*v*w

    Where w is the angular velocity and v is the linear velocity.

    3. The attempt at a solution

    I really just need help on understanding how the Coriolis acceleration in this problem is depicted. My dynamics book is extremely confusing on this part, so much so that my professor advised us to not even read it. His simple explanation was that the coriolis accel. is found by rotating your linear accel in the direction of the rotation by 90 degrees. In this problem, there are two angular velocities being applied, so I'm confused as to which one affects the coriolis accel.

    Also, I would really appreciate just a basic explanation of what the coriolis accel. is, as my professor just gave us the eqn. and the little tip on finding it. Thank you!

    when the observer is a non inertial one ,that is he himself is rotating ,his measurement frame of reference will be rotating and he observes some pseudo forces like centrifugal, coriolis etc. so you must do the analysis of measurement from the point of view of a rotating observer and calculate the value of coriolis acceleration and as its a vector it can be expressed as cross product of velocity vector and angular velocity of rotation.
    due to coriolis acceleration on Earth the shells fired by the guns get deflected considerably ;go to sites or text book for a brief intro then try to solve the problem
