小明和小亮在做传球训练,某同学借做此情境编了一道数学题.
在如图的平面直角坐标系中,一个单位长度代表1m,小明从点
处将球传出,其运动路线为抛物线
的一部分,小亮在
处接住球,然后跳起将球传出,球的运动路线是抛物线
的一部分.
的函数表达式;
(2)设抛物线
的顶点为点
,在
轴上找一点
,求使
的值最大的点
的坐标;
(3)若小明在
轴上方2m的高度上,且到点
水平距离不超过1m的范围内可以接到球,求符合条件的
的整数值.

【推荐3】在“综合实践”活动课上,老师以“如何把实心球掷得更远?”为主题展开数学探究,下面是小林同学的探究过程,请帮助解决以下问题:
处将球(看成点)抛出,其运动路线是抛物线,示意图如图1所示.当球运动到距
的水平距离为
时,达到最大高度为
.
①求抛物线的解析式;
②求投掷距离
.
(2)根据体育老师建议,第二次练习时,小林在正前方
处(如图2)架起距离地面高为
的横线.球从点
处被抛出,恰好越过横线,测得投掷距离
.
①请求出小林此次投掷实心球的最大高度;
②结合小林两次投球的最大高度的变化量,及“如何把实心球掷得更远?”请给小林提出一条合理的训练建议.
