determine the angular velocity if 11.3 revolutions are completed in 3.9 seconds

11.3 revs/39 sec

= 11.3(2π)radians / 39 seconds
= (113/195)π radians/s or appr 1.82 rad/s

To determine the angular velocity, we need to convert the number of revolutions completed into radians and divide it by the time taken.

1 revolution is equal to 2π radians.

Given that 11.3 revolutions are completed in 3.9 seconds, we can calculate the angular velocity as follows:

Number of revolutions completed = 11.3 revolutions
Time taken = 3.9 seconds

Convert revolutions into radians:
1 revolution = 2π radians
11.3 revolutions = 11.3 * 2π radians

Angular velocity = (11.3 * 2π radians) / 3.9 seconds

Now, we can calculate the angular velocity.

To determine the angular velocity, we need to use the formula:

Angular velocity = (Angle covered) / (Time taken)

In this case, we are given that 11.3 revolutions are completed in 3.9 seconds. Since 1 revolution is equal to 360 degrees, we can convert the given angle to degrees:

Angle in degrees = 11.3 revolutions * 360 degrees/revolution

Angle in degrees = 4072 degrees

Now, we can substitute the values into the formula to find the angular velocity:

Angular velocity = 4072 degrees / 3.9 seconds

Simplifying this expression, we get:

Angular velocity ≈ 1045.13 degrees per second

Therefore, the angular velocity is approximately 1045.13 degrees per second.
