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?
i'm not sure what you mean by "think of speed", but the way we measure it is by plugging the numbers into this formula: distance divided by time. if you are trying to find an average speed, then your formula would be: total distance divided by total time. i hope this ! : )
here, i hope this .
it's d) they study different areas of science and have different scientific focuses.
