You throw a stone vertically upward with an initial speed of 6.3 from a third-story office window.
1. If the window is 10 above the ground, find the time the stone is in flight.
2. Find the speed of the stone just before it hits the ground.
谁帮我做一下这道题啊,因为我没有完全读懂,所以没有做对,教教我啊

简单说一下好了,从一个3层的窗口向上以6.3的初速度扔石头.
1 如果窗口距地面的距离是10,求石头在空中飞行的时间
2 求石头落地瞬间的速度
问题补充：那么A好像也对啊？为什么不选呢？ 选C 初速度为v，s1=vTA显然是错的，v=s/t,（S1 S2）/2T 表示的是在2T的时间内，该物体的
翻译问题.
从三楼窗口垂直向上抛一块石头 初始速度是6.3（单位？？）
如果窗口离地面10米高，求石头从抛起到落到一楼地面的时间
当它落地瞬间时的速度
