Hi, here we have to solve the following problem.
00:02
The stick has a length of 2 meters and the mass of the stick, let's call it m1, is 0 .175 kilograms.
00:14
So here, mass of half a kilogram, m2, is attached to the stick as a distance of 60 centimeters from the center.
00:30
How could we solve it? so let's show here l1, now let's show the center, and here let's show the distance x.
00:44
So that is m2.
00:48
The stick rotates with an angular speed of 6 .40 radians per second.
01:01
In equation a, we have to find angular momentum relative to the axis which passes through the center.
01:11
It means that we have to determine the angular momentum.
01:17
That's mass of the stick, length squared over 12, plus m2 x squared...
