Explain how a child "pumps" on a swing to make it go higher? On the basis of the law of conservation angular momentum, discuss why a helicopter must have more than one rotor (or propeller). Discuss one or more ways the second propeller can operate in order to keep the helicopter stable. A wheel is rotating freely about a vertical axis with a constant angular velocity. Small parts of the wheel come loose and fly off. How does this affect...

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...
