A merry-go-round spins freely when Diego moves quickly to the center along a radius of the merry-go-round. As he does this, it is true to say that the moment of inertia of the system decreases and the angular speed decreases. the moment of inertia of the system decreases and the angular speed remains the same. the moment of inertia of the system increases and the angular speed decreases. the moment of inertia of the system increases and the angular speed...

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...

Review Constants i Periodic Table Ice skaters often end their performances with spin turns, where they spin very fast about their center of mass with their arms folded in and legs together. Upon ending, their arms extend outward, proclaiming their finish. Not quite as noticeably, one leg goes out as well Part A Suppose that the moment of inertia of a skater with arms out and one leg extended is 3.0 kg mº and for arms and legs in is...
