A turntable of mass 5.00 kg has a radius of 0.094 m and spins with a frequency of 0.532 rev/s. What is it's antique momentum? Assume the turntable is a uniform disk.
______ kg m^2/s
I got 0.012 but it came out wrong
______ kg m^2/s
I got 0.012 but it came out wrong

Moment of inertia, I = (1/2)mr^2. Work it out from your values.
Angular velocity, ω = 2pi x 0.532 radians/second
Angular (not antique!) momentum = Iω
It should come to 0.074 kg.m^2/s (or Js)
