例1在排球运动中,为了使从某一位置和某一高度水平扣出的球既不触网、又不图1出界,扣球速度的取值范围应是多少?已知网高H,半场长L,扣球点高h,扣球点离网水平距离s,求:水平扣球速度v的取值范围.解析假设运动员用速度vm ax扣球时,球刚好不会出界,用速度vm in扣球时,球刚好不触网 Example 1 In the volleyball game, in order to make the ball buckled from a certain position and a certain height level neither touch the net nor the map 1 out of bounds, what is the range of the spiking speed? Known net height H, The half length L, the spike height h, the spike distance from the net distance s, find: horizontal spiking speed v range of values. Analytical suppose that the player uses the speed vm ax to smash the ball, the ball just does not out of bounds, with Speed ​​vm in spiking, the ball just doesn’t touch the net
