Each of the following objects has a radius of 0.180 m and a mass of 2.65 kg, and each rotates about an axis through its center (as in the table below) with an angular speed of 41.4 rad/s.


Find the magnitude of the angular momentum of each object.
a) a hoop ___ kg m/s
b) a solid cylinder ___ kg m/s
c) a a solid sphere ___ kg m/s
d) a hollow spherical shell ___ kg m/s

  • physics - ,

    L=Iω

    I(hoop) =mR²
    I(sol.cyl)= mR²/2
    I(sol.sph) =2 mR²/5
    I(hol.sph) =2 mR²/3
