  • Consequently, for this object the position y, at any time t is known to be 15+10t-5t^.

    因此,对这个物体来说,在任意时刻的位移y,就应该为15+10t-5t^

  • I think you can tell by analogy with what I did in one dimension that the position of that object at any time t is going to be the initial position plus velocity times t plus one half a t square.

    你们可以类比一下我在一维情况下的结论,这个物体在任意时刻 t 的位移,等于初始位移,加上 v ? t + 1/2 ? a ? t^2
