Answer 1

hiiii dear______❤️❤️❤️

good morning_______________✌️✌️✌️✌️




the wheel rotates one time, it moves an angle of 2π radians.


To determine the time for one revolution, divide 2π radians by 3 rad/s. 

t = 2π/3 
The time is approximately 2.1 seconds.

Answer 2

Answer:

Given-wheel is turning at 3rad/sec

To find--the time it takes to complete one revolution

Solution -

the wheel rotates one time =an angle of 2π radians

Time= 2π radians / 3 rad/s

time=2.1 seconds.

The time is approximately 2.1 seconds.
