Interpreting Dual Time Solutions in Trajectory Reports
As a pyrotechnics technician, when you use the projectile motion model to calculate the time it takes for a firework to reach a target height, you typically obtain two distinct positive values for time (t). Based on the model, state the physical reason why both of these positive values are considered valid and must be recorded in your flight report.

As a pyrotechnics technician calculating the flight path of a firework, you find two positive time values for when the firework reaches a height of 260 feet. True or False: Both of these time values are physically meaningful for your safety report.
A pyrotechnics safety technician is documenting the flight of a firework shot at 130 feet per second. When solving for the time it takes to reach 260 feet, the technician identifies two positive solutions: 3.6 seconds and 4.6 seconds. According to the projectile motion model, what does the 4.6-second solution represent?
As a pyrotechnics safety technician, you are reviewing the trajectory data for a firework launched at 130 feet per second. Match each component of the projectile motion model to its physical interpretation in your safety report.
As a pyrotechnics safety technician, you must follow a standard procedural strategy to determine the exact moments a firework reaches a safety-critical height. Arrange the following steps in the correct order to solve for the time () using the projectile motion model.
Interpreting Dual Time Solutions in Trajectory Reports
In a pyrotechnics trajectory report, a technician identifies two positive time solutions for a firework reaching a target height. This occurs because the firework passes the target height once while it is rising and a second time while it is ____.
