37、3A5P4V5名师精编优秀教案2112Hhgt，11 1sv t解得：13 10vm/s。球恰好落在边界线时，设击球速度为v2，根据平抛运动的规律有：2212Hgt，22 2sv t解得：212 2vm/s。所以，球既不触网也不越界的速度范围是：3 10m/sv12 2m/s；（2）当球刚好触网又压底线时，设此时击球的高度为h，击球速度为0v，球刚好触网时有：2312hhgt，0 33v t球刚好压底线时有2412hgt，0 439v t消去v0，代入数值解得：3215hm 2.13m。即击球高度小于2.13m 时，无论水平击球的速度多大，球不是触网就是越界。11【答案】下移58h【解析】题目

38、中要求“两水平射程相等”，当两图线的交点正好位于地面上时，则两物体的水平射程相等。根据平抛运动规律可知，两物体初速度分别为：ghsv42101、ghsv2202。设AB下移的距离为x，根据移动后两物体的水平位移相等列方程：v01 t1 v02 t2代入数据得到：文档编码:CW10D4K7Z7M3 HA2K4C10V6W10 ZZ4J3A5P4V5文档编码:CW10D4K7Z7M3 HA2K4C10V6W10 ZZ4J3A5P4V5文档编码:CW10D4K7Z7M3 HA2K4C10V6W10 ZZ4J3A5P4V5文档编码:CW10D4K7Z7M3 HA2K4C10V6W10 ZZ4J3A5P
