Finding minimum speed given position vector. - Physics Forums
2011年4月11日 · Finding minimum speed given position vector. In summary, using the position vector r (t) = < t^2, 6t, t^2 − 24t >, the minimum speed of the particle can be found by taking the derivative of v (t) = r' (t) and setting it equal to zero. The minimum of the function f (t) = 8t^2 - 96t + 612 can then be found, and plugging the resulting t value ...
