A playground merry-go-round with an axis at the center (radius R = 1.3 m and rotational inertia | = 1.2 x 103 kgm2) is initially rotating at angular velocity w = 0.21 rad/s clockwise). A girl of mass m = 51 kg is running at speed vo in a direction tangent to the disk of the merry-go-round, intending to jump on to the point labeled with the green "x" (she is indicated by the purple circle in the figure). With what speed does the girl need to run in order that the merry-go-round will stop rotating after the girl has jumped on at the edge? [Hint: treat the girl as a point mass located at a distance R from the axis]. Your answer should be in m/s, but enter only the numerical part in the box. R Wo
