(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In the experiment that I have performed, the ball was thrown upward and caught once it reached its initial position. The data was recorded using the graphical analysis program. The graph produced is a parabola. The parabolic curve was generated showing the values of three parameters: A:-4.453, B:9.835, C:-3.565.

I need to:

1). 1.Interpret the meaning of the fit coefficients A, B and C.

2). Find out the value of the acceleration due to gravity predicted by the experiment. Compare this to the expected value, and calculate the percentage difference.

3). Calculate the quantity −B/(2A), including units, and give a physical meaning to this quantity?

I am stuck, as I have not touched the physics book for more than 10 years. Any help will be appreciated.

2. Relevant equations

Y = A t2 + B t + C

3. The attempt at a solution

1). The coefficient A is acceleration, B - velocity, C -initial position of the ball?
