In this question we are asked to find out that the average angular acceleration depends on what factors.
00:09
So, as we know, that average angular acceleration is nothing but it is denoted by a ratio of change in angular velocity divided by change in time.
00:20
So suppose at any instant the initial angular velocity is omega initial and at the 1 and at certain time t2, the angular velocity is omega final.
00:34
Now in between this period, the value of alpha is changing.
00:38
Alpha is variable in between this time.
00:42
So, we will calculate the average alpha, the average value of angular acceleration and that is given by change in angular velocity which is omega -final minus omega -incial divided by the time period which is t2 minus t1.

This is how you calculate the average angular acceleration...
