Question

O O 1 point A girl is sitting on the outside edge of a spinning merry-go-round. She then starts to walk toward the center. The merry-go-round starts to spins at the original speed. spin slower O spin faster

Answer 1

lg :-) Solni Moment of inertia is given as, - MR? R Radius m mass. As the girl walks toward the centre, & and this decreases moment of inertia. decreases, Now, as the angular momentum, L-Ion is conserved, so with the decrease in moment of inertia, I, the value of angular speed, and should increase (an and IL 17 Thus, if the girl starts to walk toward the center, the merry-go-round starts to spin faster. Hence, 3rd option is correct
