On the picture below you see the motionless black sphere and the green rod rotating around it. At the Position A the rod is motionless, and then it begins rotating and increases this rotational speed up to Position B (you can notice it-the color gradually changes from light green to dark green). After Position B the rod rotates at constant speed
I would like to know how I can calculate the acceleration between A and B positions when the rod increases the rotational speed. I know how to compute the acceleration when the rod rotates at the constant speed: a=v^2/r, but what about the situation that I would like to find out? In other words when the rod quickens let’s assume that length of the rod is 45 meters and it takes 200 seconds to reach Position B from A. So, is there any formula for this purpose?
