FE Exam Prep | Projectile Motion & Radius of Curvature (Step-by-Step Solution)

*🧪 Try this problem interactively:* https://www.fe-interactive.com/practi... *📺 Full FE Mechanical Problem Playlist:*    • FE Example Problems   --- *🧠 FE Exam Prep | Projectile Motion – Radius of Curvature at the Peak* Struggling with projectile motion on the *FE exam**? In this video, we solve a classic **FE-style problem* that asks you to find the *radius of curvature at the peak* of a projectile’s path. This concept relies on understanding *velocity and acceleration* along curved motion using **normal–tangential (n–t) coordinates**. This *step-by-step breakdown* reinforces core ideas from *Kinematics* and *Engineering Dynamics**, which appear on the **FE Mechanical**, **FE Civil**, and **FE Other Disciplines* exams. --- *✅ You’ll Learn How To:* Analyze velocity and acceleration directions at the peak Break motion into normal and tangential components Apply the formula \( \rho = \frac{v^2}{a_n} \) Understand why tangential acceleration is zero at the peak --- *📘 Topics Covered in This Video:* • Projectile motion and curved paths • Normal and tangential coordinate system • Acceleration components in 2D motion • Radius of curvature concept • FE-style dynamics and kinematics strategies --- *💡 Why This Matters:* Projectile motion shows up across multiple FE exam disciplines. Understanding curvature and acceleration along a path is essential for *Civil**, **Mechanical**, and **Other Disciplines* test-takers — and it’s easy to miss if you're not confident with vector breakdowns and motion analysis. --- *💬 Got questions or topics you’re struggling with?* Drop a comment below — I read every one and make videos based on what YOU need help with. --- *📈 Want more practice?* Visit [https://www.fe-interactive.com](https://www.fe-interactive.com) for: • 500+ FE-style practice questions • Full-length timed exams • Smart analytics and progress tracking • TI-36X Pro calculator tips • Practice using the NCEES FE Reference Handbook • Referral code bonuses and more! --- *🔔 Like, subscribe, and turn on notifications* for more FE prep content every week! --- *#FECivil #FEMechanical #FEOtherDisciplines #FEExamPrep #ProjectileMotion #RadiusOfCurvature #EngineeringDynamics #Kinematics #EngineeringExam #PassedTheFE #EngineerInTraining #FutureEngineer #EngineeringStudent* ---
