The trajectory of a balloon that rises 2 feet per second is modeled to find how high the balloon will be in 5 minutes.

Answer 1

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 typically follows a parabolic path, which can be described by a quadratic equation. The other scenarios involve either linear growth (like the savings account and piggy bank) or linear motion (like the balloon rising), which do not require quadratic equations.
