provide correct answer and explanation

Now, assume going forward that the position is given by the equation z(t) = 0.2t3- 2.4t + 7.21 -5. Enter this function in the Expression Evaluator as r(t) = 0.2+ txt .t - 2.4 x txt + 7.2 . t -5 and run the simulation by clicking the Play button in the Record mode, waiting until the person collides with the wall to select the Pause button. Consider the person's motion from the beginning until the moment just before colliding with the brick wall. Part E Which of the following statements is true of the position at f = 1.0 s? The position is decreasing at a rate decreasing in magnitude O The position is decreasing at a rate increasing in magnitude The position is increasing at a rate decreasing in magnitude The position is increasing at a rate increasing in magnitude
