    "abstract": "Optimum projection angles for achieving maximum horizontal range in throwing\nand jumping events are considerably less than 45 degrees. This unexpected\nresult arise because an athlete can generate a greater projection velocity at\nlow projection angles than at high angles. The range of a projectile is\nstrongly dependent on projection speed and so the optimum projection angle is\nbiased towards low projection angles. Here we examine the velocity-angle\nrelation and the optimum projection angle in selected throwing and jumping\nevents.",
