To help you find the value of \( a \) in the equation modeling the path of a golf ball, it's typically related to the quadratic equation of the form \( y = ax^2 + bx + c \), where \( a \) determines the direction and the width of the parabola.
Please provide the data from the table or specific points that represent the path of the golf ball, and I can assist you in deriving the equation and determining the value of \( a \).
