To measure g (the acceleration due to gravity) the following experiment is carried out. A ball is dropped from the top of a 30-m-tall building. As the object is falling down, its speed r is measured at various heights by sensors that are attached to the building. The data measured in the experiment is given in the table. In terms of the coordinates shown in the figure (positive down), the speed of the ball v as a function of the distance x is given by v2 = 2gx. Using linear regression, determine the experimental value of g.

Explanation / Answer

v^2/2x and taking the average value through those obsevations the value is 10.02
