16. Angular Momentum / Spinning on String of Variable Length / Problem 19
A tiny marble with a mass of 15 grams is moving in a frictionless circular path with a radius of 50 cm. The marble moves at an initial speed of 4 rad/sec. The radius then decreases to half its original size. Is the angular momentum of the marble conserved? Explain your answer.
