Here, when it makes this rounding curve the velocity is positive here, but on this side it's negative so what does that mean for the acceleration?

这里，就在曲线的拐角，速度一开始是正的，不过在另一边就成了负的，就加速度而言这又意味着什么呢？

You cannot have a spring pulled only at one side, because then it will then accelerate with infinite acceleration in that direction.

你不可能对弹簧只施加一边的拉力,因为那样的话弹簧就会以无穷大的加速度加速,就在这个方向上
