A large horizontal circular platform (M=120.1 kg, r=3.45 m) rotates about a frictionless vertical axle. A student (m=73.3 kg) walks slowly from the rim of the platform toward the center. The angular velocity w of the system is 3.9 rad/s when the student is at the rim. Find w (in rad/s) when the student is 2.47 m from the center.(adsbygoogle = window.adsbygoogle || []).push({});

Does the angular velocity w is not the same everywhere in the circular platform?...

i put 3.9 rad/s and the answer was wrong
