Please Help! I need to turn this in ASAP. I can’t find the answer... If you could show the work it would be very very appreciated!
(Part 1)
A merry-go-round rotates at the rate of 0.4 rev/s with an 99 kg man standing at a point 2.5 m from the axis of rotation. What is the new angular speed when the man walks to a point 1 m from the center? Consider the merry-go-round is a solid 73 kg cylinder of radius of 2.5 m. Answer in units of rad/s.
(Part 2)
