4)A large disk of mass Md and radius R is spinning in a horizontal plane about a vertical axis through its center with a given angular velocity of omega. A person of mass Mp (initially at the center of the disk and not spinning, let's say) then walks out to the edge of the disk (yes, the disk is that large!). Find the final angular velocity of the disk (with the person standing on its edge).Treat the person as a...
A uniform disk of mass m and radius R lies in a vertical plane and is pivoted about a point a distance l_cm from its center of mass in (Figure 1).
A uniform disk of mass m and radius R lies in a vertical plane and is pivoted about a point a distance l_cm from its center of mass in (Figure 1). When given a small rotational displacement about the pivot, the disk undergoes simple harmonic motion. Part ADetermine the period of this motion. Use the notation lcm for the distance lcm.

A penny is placed at the outer edge of a disk (radius = 0.147 m) that rotates about an axis perpendicular to the plane of the disk at its center. The period of the rotation is 1.70 s. Find the minimum coefficient of friction necessary to allow the penny to rotate along with the disk.

A bar 1.91 m long pivots in a vertical plane about one end. The
first 0.37 m of this rod is made of nonconducting material, but the
outer part are made of iron (see Figure). The apparatus is within a
uniform 1.2 T magnetic field oriented at right angles to the plane
in which the bar rotates. At what angular speed would you need to
rotate this bar to generate a potential difference of 11.8 V
