Chapter 11, Problem 66GP
A merry-go-round with a moment of inertia equal to 1260 kg·m2 and a radius of 2.5 m rotates with negligible friction at 1.70 rad/s. A child initially standing still next to the merry-go-round jumps onto the edge of the platform straight toward the axis of rotation causing the platform to slow to 1.25 rad/s. What is her mass?
