we know angular momentum = (position vector relative to origin) x (linear momentum) - linear momentum = 10kgV -what is the position vector relative to origin? -what angle does the position vector make with the linear momentum. -- if < 180 angular momentum = 0.

Homework Statement 10kg is attached to the end of a string, which is thread through a vertical tube. The string and the tube always make a 90 degree angle. The distance from the tube to the mass is R and the velocity at which it rotates is V. How much work is done to shorten the distance...

The mass of the disc is M and the radius is R. The problem states: A disc completes 44 revolutions as it slows from an angular speed of 1.5 rad/sec to a complete stop. 1)W/ acceleration constant, what times is required for it to come to rest? 2) what is the angular acceleration...
