排球教练向作者提出了一个排球中的物理问题:“运动员应跳多高去扣球才能使球过网并落在对方场地预想的区域内?”作者在本文中应用抛物体的运动公式及有关的力学知识推导证明这个问题,并获得了当球落在对方场地的预想区域时,运动员跳起扣球的高度公式.
Volleyball coach put forward to the author a physical problem in volleyball: “athletes should jump to smash the ball in order to make the ball over the network and fall in the other side of the site expected area?” In this paper, the application of parabolic motion equations and related The knowledge of mechanics is deduced to prove this problem and obtain the height formula for the athlete to jump the spike when the ball falls in the expected area of the opponent’s field.
