Optimum projection angles for achieving maximum horizontal range in throwing and jumping events are considerably less than 45°. This unexpected result arises because an athlete can generate a greater projection velocity at low projection angles than at high angles. The range of a projectile is strongly dependent on projection speed and so the optimum projection angle is biased towards low proje...
