How to determine the time required for rocket launch to the highest point through mathematical modeling
It can be determined by the vertex of the quadratic function. Let x be the launch time, y be the height of the rocket from the ground, let the quadratic resolution function be y = ax 2+bx+c, and then change it to vertex y = a (x-h) 2+k. When x=h, the maximum height of the rocket from the ground is k.
