Unformatted text preview: given or asked for? Yes Impulse-Momentum problem Draw a FBD and Start/End Momentum diagrams Consider Impulse/Momentum in axial directions Consider Angular Momentum about a point. (Vector method) Is there start and end position given, but no time? Yes Work-Energy problem Draw Start/End position diagrams Write Work-Energy Equation (Scalar method) Is there an object rotating freely in a horizontal plane Yes Conservation of Angular Momentum Draw Start/End Momentum diagrams Consider Angular Momentum around a vertical axis. (Vector method) If you still dont have the answer you need, maybe it requires more than one approach. Go back to the start and think some more....
