Now in this question we are given with four parts.
00:04
So the first part says that we have to find out the angular velocity of disc.
00:15
So the angular velocity of disc is the sum of angular velocity of shaft, shaft plus angular velocity disc relative to shaft, shaft.
00:48
So now the angular velocity comes out to be minus 3 radian per second plus 8 radian per second giving us 5 radian per second.
01:02
So this is the answer of our first part.
01:08
Now our b part says that we have to find the angular acceleration of the disc.
01:15
So since angular acceleration is given by the formula d omega by dt.
01:27
So since the angular velocity of disc is increasing at a constant rate of 3 radian per second, so the angular acceleration comes out to be 3 radian per second.
01:39
Alright.
01:40
This is the angular acceleration.
01:42
Now c part says that we have to find out the displacement of point a relative to o...
