The Quest for the Perfect Launch

Scenario: The Quest for the Perfect Launch Background: In the innovative city of Vectropolis, the annual Science Fair is featuring a contest to design the perfect launch for a new miniature hovercraft. The hovercraft's movement can be controlled by adjusting its velocity in two dimensions, and the goal is to create a motion path that satisfies certain conditions using parametric equations. Objective: As a bright young physicist, you are excited to enter the contest. Using the Motion with Variable Velocity Applet, your task is to plan the hovercraft's trajectory, ensuring it passes through specific checkpoints in the 2D space. Investigation Steps: 1. Understanding the Parameters: - Familiarize yourself with the applet's controls for setting the hovercraft's velocity in the x and y directions. - Determine the starting position and understand how the parametric equations will govern the hovercraft's path. 2. Planning the Trajectory: - Input parametric velocity functions that you believe will guide the hovercraft through the designated checkpoints. - Use the applet to simulate the hovercraft's movement and observe its path. 3. Refining the Path: - Adjust the velocity functions based on the results of your initial test to better align with the checkpoints. - Utilize concepts of physics and calculus to optimize the hovercraft's trajectory. 4. Presenting Your Findings: - Prepare a presentation for the Science Fair judges explaining your design process and how you used the applet to achieve the desired motion path. Questions for Investigation: 1. Discovery Question: - How do different parametric functions for velocity affect the shape and nature of the hovercraft's trajectory? 2. Optimization Challenge: - What strategies can you use to minimize the distance traveled by the hovercraft while still passing through all checkpoints? 3. Real-world Application: - Discuss how this simulation relates to real-world scenarios, such as programming drones or planning satellite orbits. 4. Reflection: - Reflect on the importance of simulation tools in the process of scientific discovery and engineering design.
