Yeah, so in the question we have given that in an amusement park, passengers are seated in a circle, horizontal circle of radius 7 .5 meters.
00:11
Now the question says that here initial angular speed is zero.
00:26
Time taken is 21 seconds.
00:34
Maximum rotational speed.
00:36
Max rotational speed, that is omega dash is equal to 1 .4 radian per second.
00:54
From here we can calculate the angular acceleration.
00:58
So angular acceleration is equal to alpha is equals to omega dash minus omega, divided by t.
01:17
So, omega dash is 1 .4 radian per second.
01:21
So, 1 .4 minus omega is 0.
01:25
Initial angular speed is 0, so 0.
01:28
Divided by time taken is 21 seconds...
