The angular velocity of the Ferris wheel is 8.38 radians/minute.

What is angular velocity?

"The angular velocity is the time rate at which an object rotates or revolves about an axis."

It takes 45 seconds for her chair to complete a full revolution.

Therefore, in terms of revolution per minute, the speed is

= 60/45 revolutions/minute

= 4/3 revolutions/minute.

We know, 1 revolutions = 2π radian

Therefore, 4/3 revolutions/minute

= (4/3) × 2π radians/minute

= 8.38 radians/minute

Hence, the angular velocity is 8.38 radians/minute.
