It sounds so esoteric, but the title of this paper, available via the Sciencebase Physics ePrints page, is all about learning how to throw a ball the furthest. To quote from the authors conclusion: “The present solution …is based on the widely applicable technique of change of variables. Although this may be implicit in the algebraic variant of the solution, both variants may serve as an illustration of the usefulness of the technique in simplifying otherwise complicated calculations.”
See, I told you it wasn’t esoteric.
