A disk with moment of inertia 9.15 × 10−3 kg∙m^2 initially rotates about its center at angular velocity 5.32 rad/s. A non-rotating ring with moment of inertia 4.86 × 10−3 kg∙m^2 right above the disk’s center is suddenly dropped onto the disk. Finally, the two objects rotate at the same angular velocity ?? about the same axis. There is no external torque acting on the system during the collision. Please compute the system’s quantities below. 1. Initial angular momentum ??...

(c) An electric dipole consists of 1.0 g spheres charged to +3.0nC at the ends of a 15 cm long non-conducting rod of mass 4g (don't try to look up "electric dipole", it won't help you. For the sake of this problem, it's just a fancy word for what I just described). The dipole rotates on a frictionless pivot at its center. The dipole is held perpendicular to a uniform electric field with a field strength 1000 V/m, then released....

A moon of mass m orbits around a non-rotating planet of mass M with orbital angular velocity . The moon also rotates about its own axis with angular velocity .
1. A moon of mass \(m\) orbits around a non-rotating planet of mass \(M\) with orbital angular velocity \(\Omega\). The moon also rotates about its own axis with angular velocity \(\omega\). The axis of rotation of the moon is perpendicular to the plane of the orbit. Let \(I\) be the moment of inertia of the moon about its own axis. You can assume \(m<<M\)so that the center ofmass of the system is at the center of the planet.(a) What is...

10*) The Sun has approximate radius 7×108 m, and rotates around
its axis once every 27 days. a) Find its angular velocity in rad/s,
and (assuming it is a uniform sphere) write a formula for its
angular momentum expressing it in terms of its mass M (you do not

To apply the principle of angular impulse and momentum to
describe a particle's motion.
The moment of a force about a point O, fixed in an
inertial coordinate system, MO, and the angular momentum about the
same point, HO, are related as follows:
∑MO=H˙O
where H˙O is the time derivative of the angular momentum,
HO=r×mv. Integrating this equation with respect to time yields the
following equation:
∑∫t2t1MO dt=(HO)2−(HO)1
This equation is the principle of angular impulse and momentum,
and it...
