D Date: -- Due Date: 5/4/2022 11:59:00 PM End Date: 5/21/2022 11:59:00 PM (5%) Problem 2: Three children are riding on the edge of a merry-go-round that is a disk of mass 106 kg, radius 19 m, and is spinning at 19 rpm. The children have masses of 23.2 kg, 26.4kg, and 322 kg. Randomized Variables M106 kg m = 232 kg y = 26.4 kg mj = 32.2 kg 1.9 m f-19 rpm & If the child who has a mass of 26.4 kg moves to the center of the merry-go-round, what is the new magnitude of angular velocity in rpm?

(7%) Problem 1: An ice skater is spinning at 5 revis and has a moment of inertia of 0.32 kg m. 339 Part (a) Calculate the angular momentum, in kilogram meters squared per second, of the ice skater spinning at 5.8 rev/s. 111.66 ✓ Correct! 334 Part (h) He reduces his rate of rotation by extending his arms and increasing his moment of inertia. Find the value of his moment of inertia (in kilogram meters squared) if his rate of rotation decreases to Stev/s. 11.24 ✓ Correct *33% Purt (e Suppose instead he keeps his arms in and allows friction of the ice to slow him to 3.25 rev/s. What is the magnitude of the average torque that was exerted, in Nm, if this takes 4 s?
