Please answer part b.

Question 2 This question contains multiple parts. Make sure to read all the instructions and answer each part. Three children are riding on the edge of a merry-go-round that is a solid disk with a mass of 106 kg and a radius of 1.79 m. The merry- go-round is initially spinning at 12.7 revolutions/minute. The children have masses of 31.8 kg, 26.2 kg and 38.9 kg. Image size: s M L MaxPart a (1 points) If the child who has a mass of 26.2 kg moves to the center of the merry-go-round, what is the new angular velocity of the system in units of revolutions/minute? Please enter a numerical answer below. Accepted formats are numbers or "e" based scientific notation e.g. 0.23, -2, 1e6, 5.23e-8 15.4 revolutions/minute Your Answer Your actual answer was 15.388 which differs from the answer above by a small rounding error or significant figures. Check with your instructor how this will be graded in a testing situation Saved CHECK ANSWER 1 of 6 checks used Part b (1 points) What is the relative change in the system's rotational kinetic energy as a result of the child moving inward? Your answer should be expressed as a ratio of AKE _ KE-KE. KE, KE, , where K E; is the initial kinetic energy and K Ef is the final kinetic energy. Be sure to correctly indicate the sign: positive means KE was gained, negative means KE was lost. Please enter a numerical answer below.
