4. Trajectory estimation, Part I 2 points possible (graded) Note: For this problem, you may find this summary useful. (This is also available at the bottom of Lecture 15, 12. Multiple parameters; trajectory estimation.) The vertical coordinate ("height") of an object in free fall is described by an equation of the form where , and are some parameters and stands for time. At certain times , we make noisy observations , respectively, of the height of the object. Based on these observations, we would like to estimate the object's vertical trajectory
