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...
