The condition imposed by the construction of the problem and the laws of motion is that f''(t) = sqrt(t), and that f''(t) = 0 => F(t) = 0. The function given as an example in the article, f(t) = {(1/144) (t-T)^4, t >= T | 0, t < T}, obeys both laws, just as much as f(t) = 0 does. I'm not sure what the fourth derivative has to do with this argument. |
