In this problem, we are also to calculate the angular momentum of the satellite about the point a at the given instant of time.
00:09
So we need to calculate this h -a.
00:14
This is the angular momentum.
00:17
In order to calculate angular momentum, we need to calculate the moment of inertia.
00:22
So we can write i -x -prime is equals to i -y -prime, and this is equals to the mass, which is equal to 200 k -g, into 0 .5 meter whole square.
00:36
So this will give us the moment of inertia about these points as 50 kg meter square.
00:46
Similarly we can write the moment of inertia about z prime as a z prime is equals to 200 kg into 0 .3 meter whole square.
01:00
So this this will give us 18 .0 kgmetre square.
01:08
Now by applying the symmetry, we can write the products of the inertia of the satellite about these axes as i, x prime, y, prime is equals to i, y, prime, z prime, and this is equals to i, x prime, z prime, is equals to zero.

The angular velocity of the slide is written as omega is equal to into 600i plus 300 jay plus 1 ,250k into radian per second.
01:54
So this is the angular velocity.
01:57
This gives us that this omega x prime is equals to 600 rate.
02:03
Per second, omega y prime is equal to 300 radian per second, and omega z prime is equals to 1 ,250 radian per second...
