Rotation HCV Q. No. 57 Rotating Platform

In this video, we solve HCV (Rotational Mechanics) Question No. 57, a classic application of Angular Momentum Conservation that frequently confuses students. 👉 A platform is initially at rest. 👉 A kid standing on the rim throws a ball horizontally, tangential to the rim. 👉 The speed of the ball is v as observed by his friend. 👉 What is the angular velocity with which the platform starts rotating? This problem is extremely important because it tests: • ✅ Conservation of angular momentum • ✅ Choice of correct frame of reference • ✅ Tangential velocity vs relative velocity • ✅ Conceptual understanding beyond formulas 📌 Must-watch for: • JEE Main & JEE Advanced aspirants • NEET Physics students • Class 11 & 12 – Rotational Mechanics • Students preparing HCV thoroughly 🎯 Watch till the end for a clear physical explanation and exam-ready approach. 📚 Chapter: Rotational Mechanics 📖 Book: H.C.

Suppose the platform of the previous problem is brought to rest with the ball in the hand of the kid standing on the rim. The kid throws the ball horizontally to his friend in a direction tangential to the rim with a speed v as seen by his friend. Find the angular velocity with which the platform will start rotating.
