Two masses are connected to the ends of a homogeneous rod
Two masses (m1 = 4.35 kg, r1 = 12.0 cm, m2 =9.40 kg, and r2 = 20 cm) are connected to the ends of a homogeneous rod (L = 82.5 cm, m = 11.3 kg) as shown below. Find the x-coordinate for the center of mass of the three-object system in centimeters.

A
light, rigid rod of length l = 1.00 m joins two particles,
with masses m1 = 4.00 kg and
m2 = 3.00 kg, at its ends. The combination
rotates in the xy plane about a pivot through the center
of the rod (see figure below). Determine the angular momentum of
the system about the origin when the speed of each particle is
3.20 m/s.

Two equal masses of 3.0 kg are at the ends of a 90-cm-long massless rod. The rod spins at 7.0 rev/s about an axis through its center of mass. Suddenly, a compressed gas expands the rod out to a length of 180 cm. What is the rotation frequency after the expansion? (rev/sec is frequency)( use conservation of angular momentum.)
