Model Rocket Trajectory Analysis

The video tutorial explains how to solve for vertex form in projectile word problems. It begins with setting up a model rocket problem, drawing a diagram, and identifying the vertex. The tutorial then demonstrates how to calculate the 'a' value using a reference point, specifically (0,0), and solve for the height at a specific time. The second part of the video addresses a more complex problem involving horizontal distance, requiring additional steps to find the vertex and solve for the 'a' value. The video concludes by summarizing the key steps in solving vertex form problems.
