Answer:
Angular acceleration will be
Explanation:
We have given that mass m = 0.18 kg
Radius r = 0.32 m
Initial angular velocity
And final angular velocity
Time is given as t = 8 sec
From equation of motion
We know that
So angular acceleration will be
The answer & explanation for this question is given in the attachment below.
That's the definition of pressure ... force on a given area.
So when that force increases, it's an increase in pressure.
