Calculation of tangential acceleration of point on cycloid

Hello, We need to calculate tangential acceleration of point on cycloid, function of angle "fi" and parameters like radius of wheel, angular velocity, position of point from wheel middle. We search for someone who will provide us with working function to calculate the above in matlab. If you need any more information, please send us PM. What is the output : Algorythm of this function, simulated also in Matlab How will be the project paid : After its done, it ill be paid by escrow Project has to be calculated in 4 days Explanation of what we need to calculate is in attached picture : Thanks Peter
