本文从3种典型的求解抛体运动的射程问题出发,总结出3种问题要实现射程最大需要满足的条件,将3种问题归结为一种问题,并结合抛物线的几何性质证明了要达到最大射程的通用条件. In this paper, three kinds of typical solutions to the range of projectile motion are discussed. Three kinds of problems are summed up to satisfy the maximum range requirement. The three kinds of problems are summed up as a kind of problem. Combined with the geometric properties of the parabola, General conditions of range.
