A child of mass m - 26 kg is standing at the edge of a playground merry-go-round (moment of inertia Jam - 2500 kg . m' and radius R - 2.5 m). which is initially turning at 5.8 rev / min. The child walks opposite to the direction of motion of the merry-go-round with a speed of 1.5 m/s with respect to it. She walks along its edge and completes two full revolutions, stopping at her starting point. (a) Find the speed of the merry-go-round after the child stops. State your answer in revolutions per minute. Number rev / min (b) The child then starts walking along the edge of the merry-go-round until the merry-go-round is spinning with an angular speed of 0.71 rad /s. She then jumps off the merry-go-round by leaping outward in a radial direction with respect to the merry-go-round. Find the angular speed of the merry-go-round just after the child leaps off. The coefficient of static friction between the child and the merry-go-round is 0,50 Number rad /s
