The scenario that would use a quadratic equation to solve is:

A coach models the trajectory of a ball to find out how high the player is kicking the ball.

This is because the trajectory of a projectile (such as a ball) can be described by a quadratic equation, typically in the form of a parabolic curve, where height is a function of time or distance.
