American children jokingly put "V", which resembles "horns", behind friends' heads in group snapshot.
在集体照相的时候,美国孩子常开玩笑地在朋友的脑袋后面摆出手势V,样子就像动物的角一样。
Therefore, mathematically at a given time t, we can trade t for v and put it into this formula.
因此,从数学角度来说,在给定的时刻 t,我们可以用 v 来表示 t,并代入这个式子
OK, so now we can take the result from this and put it onto a p v diagram.
好,现在我们有了结论,把它画进pv图。
If you solve for that, you find y-y0=v0^/, and if you put in the v_0 I gave you, which was what, 10?
如果你解这个式子,你会得到y-y0=v0^/,如果再把我给你的v0代入,那个数是多少 10
