r So, let's remember that the amount by which we moved, t delta r, is approximately equal to v times delta t, OK, and just using the definition of a velocity vector.
所以记住移动的量△,约等于v*△,这是用速度矢量的定义。
I know v zero x, that is v zero cosine alpha xt=t so x of t is v zero cosine alpha times t but there is no acceleration, so that's it.
并且v0x=v0cosα,那么可有得出,因为没有加速度，所以就是这样了。
