# energy of ball mill is maximum at of its speed

• #### How to Determine Maximum and Minimum

A good way to analyze maximum and minimum speed is to consider the speed function and its graph. (Or, if you're a glutton for punishment, check out the following mumbo jumbo.) Speed equals the absolute value of velocity. Velocity, V(t), is the derivative of position (height, in this problem). Thus: So, for the yo-yo problem, the speed function,
