Solved: This Equation Is A Mathematical Model For The Moti

5. This equation is a mathematical model for the motion of the ball. A model is a representation of a phenomenon or object. You can use this mathematical model to predict the location of the ball if you know the time, or the time when the ball will reach a certain position. Let's use this model to predict the time for the ball to reach the flag.
