A molecule CN can be described by a dumbbell consisting of two masses m 6. and...
6. Spinning Dumbbell Two small masses (m = 3.0 kg; M = 5.0 kg)
are attached to the ends of a thin light rod that isL = 16.0 cm
long. The dumbbell is placed vertically at the edge of a
frictionless table as shown in the diagram. The rod is struck at a
height of ? = 12.0 cm above the center of mass of the lower mass,
m, with an impulsive blow that lasts½ millisecond, and that rises
linearly...
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.

A system of two bodies consisting of a rod of mass m and length L, and a disk of mass M and radius R, moves in the x-y plane. The disk rotates about the axis attached to the rod at a distance b from its axis of rotation. The absolute angular velocity of the rod is 2, and the angular velocity of the disk relative to the rod is @. Determine the ratio E/Ho of the kinetic energy E of...
5. A diatomic molecule (like H2) can be modeled as two atoms of equal mass m, connected by a rigid massless rod of length a. The system is free to rotate in 3-D. I claim the moment of inertia of this molecule around its ceater of mass is a. (Feel free to convince yourself that factor of k is coect!) Big hint if you 're having trouble getting started: this problem is directly related to McIntyre's Ch A) The energy...
6.(16) Consider the spring-mass system shown, consisting of two unit masses m, and my suspended from springs with constants k, and ky, respectively. Assuming that there is no damping in the system, the displacement y(t) of the bottom mass m, from its equilibrium positions satisfies the 4-order equation (4) y2 + k + k)y + k_k2yz = e-2, where f(t) = e-2 is an outside force driving the motion of m. If a 24 N weight would stretch the top...
