但如果你只是需要一个恒定的速度值,那又该怎么做,那你只需要知道,这个矢量的大小。
But, if you want just the usual speed as a number, then, what will you do? Well, you will just take exactly the magnitude of this vector.
Take the difference of the two velocities and divide by the difference of the two times, and you've got the acceleration.
