A Young Girl Who Aspires to Be a Rocket Scientist

A young girl who aspires to be a rocket scientist launches a model rocket from the ground at time t = 0.The rocket travels straight up in the air, and the following graph shows the upward velocity of the rocket as a function of time: Let h be the height (or vertical displacement) of the rocket, let a be the acceleration of the rocket, and let h = 0 be the ground level from which the rocket was launched.Recall that the first derivative of displacement is velocity and that the first derivative of velocity is acceleration.Is the following a graph of the acceleration or the height of the rocket as a function of time?

A) The acceleration.
B) The height.
