Abstract: The optimal angle for the shot-put is obtained through elementary mathematics. The envelope of the parabola family is used to determine the parameters for putting shots on a slope. It is shown in the general case that the velocity of the shot in the initial putting-direction is just zero at the given height or distance when it is put in the optimal angle.
