You stand on a turn-table with arms extended out horizontally, as shown in the figure below. In each hand, she holds an 8 kg weight. In this initial state, your professor and the turn-table are rotating at a constant rate of 9 rpm. Note that each weight is held 85 cm from the axis of rotation. Your professor brings her arms, and the weights, inwards towards her axis of rotation, as shown in the figure. What is the final rotational speed, in rpm, of your professor on the turn- table? You can assume that the weights are located on the axis of rotation in this final state. Wi Wt inital rinal State stüte The turn-table has a moment of inertia of 0.31 kg m^2.

A girl is riding a spinning merry-go-round as shown in the diagram. While the ride spins, the girl moves from the outside edge to the center of the rotating platform. What happens to the angular momentum and the rotational kinetic energy of the girl/merry-go- round system? both remain the same none of these both increase angular momentum remains the same, rotational kinetic energy increases angular momentum remains the same, rotational kinetic energy decreases angular momentum decreases, rotational kinetic energy increases angular momentum increases, rotational kinetic energy decreases
