Hi, this question says that on an amusement park ride, passengers are seated in a horizontal circle of radius 7 .5 meters.
00:12
The seats begin from rest and are uniformly accelerated for 21 seconds to a maximum rotation speed of 1 .4 radiance per second.
00:20
We need to determine the tangential acceleration of the passengers during the first 21 seconds of the right.
00:27
So let us write down the given data.
00:29
So here the radius is given as 7 .5 meters, that is r is equal to 7 .5 meters.
00:46
Then it is a starting from rest.
00:48
Therefore, the angular velocity, that is the initial angular velocity is 0.
00:55
Then the final angular velocity is given as 1 .4 radiance per second.
01:06
And the time duration is also given.
01:08
The time duration t is given as 21 seconds.
01:14
We need to determine the tangential acceleration of the passengers during the first 21 seconds of the right...
