Why do we differentiate and put v=0?BB22CFD0-50B6-484E-88F2-0D5796BEFAE1.jpeg66FD0528-CECC-4B5E-A20F-C87B2DDA5645.jpegFE20B5A4-F904-48FE-8A7F-C785C3AE26F2.jpeg

Velocity is 0 when boomerang stops
Maximum / minimum displacement occurs when the velocity is 0. Differentiating displacement gives a velocity equation, since velocity is the rate of change of displacement. By setting velocity equal to 0, you are finding the turning points of the displacement graph, i.e. the maximum and minimum displacement.
