Baseball has a lot to do with physics but mostly projectiles. As a outfielder in baseball, you would want to throw the ball into infeild at a 45 degree angle. this will maximize your distance of the ball. A baseball players goal is to get teh ball infeild as fast as possible and throwing it at a 45 degree angle would help this happen. to get the player out, the ball must beat the player. therefore, overall, an outfeilder would maximize their play by continuing to throw the ball with a 45 degree angle.
