It only takes a minute to sign up. If non-conservative forces are either known or small and if energy is converted from one form to another between the locations, then any time you relate speed and position of an object at two different points conservation of energy is the most direct way to understand the problem. #=sqrt (18^2+v_y^2)# But in both cases, if you initially recognize that you have the information to work the problem with energy, you can solve it in a single step.
