| 摘 要： | 在忽略空气阻力的情况下,抛射体运动的飞行路径长度与抛射初速度的平方成正比.运用Matlab可比较容易地证明,当抛射角为56.49°时,飞行路径最长.

| Abstract: | In the absence of air resistance, the path length of a projectile motion is in direct proportion to the square of the initial projectile angle. It can be deduced with MATLAB that the path length maximizes when the initial projectile angle is 56.49°. |
