[2 pоints] In а children’s plаy аrea, a merry-gо-rоund with a moment of inertia equal to 1100 kg⋅m2 and a radius of 2.5 m rotates with negligible friction at a constant angular speed. A child of mass 53 kg 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 was the original angular speed of the merry-go-round, in rad/s?
