1. Examine the situation to determine that rotational kinematics (rotational motion) is involved. Rotation must be involved,but without the need to consider forces or masses that affect the motion.2. Identify exactly what needs to be determined in the problem (identify the unknowns). A sketch of the situation is useful.3. Make a list of what is given or can be inferred from the problem as stated (identify the knowns).4. Solve the appropriate equation or equations for the quantity to be determined (the unknown). It can be useful to think interms of a translational analog because by now you are familiar with such motion.5. Substitute the known values along with their units into the appropriate equation, and obtain numerical solutionscomplete with units. Be sure to use units of radians for angles.6. Check your answer to see if it is reasonable: Does your answer make sense?
