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 kicked ball follows a parabolic path, which can be described by a quadratic equation. The other scenarios either involve linear growth (saving account and piggy bank) or constant speed (balloon rising).
