Aperson with mass mp = 71 kg stands on a spinning platform disk with a radius of r = 1.62 m and mass md = 193 kg. the disk is initially spinning at ω = 1.8 rad/s. the person then walks 2/3 of the way toward the center of the disk (ending 0.54 m from the center). 1)what is the total moment of inertia of the system about the center of the disk when the person stands on the rim of the disk?

439.587 kgm²

Explanation:

= Mass of person = 71 kg

R = Radius of platform = 1.62 m

= Mass of disc = 193 kg

The moment of inertia of the system is given by

The total moment of inertia of the system about the center of the disk when the person stands on the rim of the disk is 439.587 kgm²

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.
