physics Each of the following objects has a radius of 0.173 m and a mass of 2.48 kg, and each rotates about an axis through its center (as in the table below) with an angular speed of 40.8 rad/s. Find the magnitude of the angular momentum of each object.
(a) a hoop= ( kg · m2/s)
(b) a solid cylinder= (kg · m2/s)
(c) a solid sphere= (kg · m2/s)
(d) a hollow spherical shell= (kg · m2/s)
