Pitcher's mounds are raised to compensate for the vertical drop of the ball as it travels a horizontal distance of 18m to the catcher.a)If a pitch is thrown horizontally with an inital speed of 32m/s,how far does it drop by the time it reaches the catcher?b)If the speed of the pitch is increased,does the drop distance increase,decrease,or stay the same?Explain.c)If this baseball game were to be played on the Moon,would the drop distance increase,decrease,or stay the same?Explain.
帮帮忙吧

当它旅行水瓶的护堤被上升为直立的滴补偿球到catcher.a的18m的地平的距离)如果以32m/s的inital生死时速程度地平地被扔，多远它随便访问它到达的时间catcher?b)如果沥青的生死时速被增加，做落下距离增加,减少,或保持一样?解释...)如果这场棒球游戏将在月亮上被游戏，将落下距离增加,减少,或一样?解释。

用软件翻译的，大概意思晓得了。球离地18米，已32米每秒的速度水平抛出，多久后落地？距离多远？如果平抛速度增加，下落距离怎么变，增加,减少,或保持一样?如果在月球上，下落距离怎么变，增加,减少,或保持一样?
简单题：当它落地时H=0.5gt^2=18 所以t=1.9S,水平距离1.9×32=60.8米
水平速度增加，下落距离不变，时间不变
月球上时间要增加，因为加速度减小

是要翻译还是要解答？
