Question

What is the angular acceleration of the flywheel?

-5 rad/s^2
-10 rad/s^2
-15 rad/s^2
-20 rad/s^2

Answer 1

The angular acceleration of the flywheel cannot be determined with the given information.

Step-by-step explanation:

The angular acceleration of the flywheel can be calculated using the formula:

angular acceleration = (final angular velocity - initial angular velocity) / time

In this case, the final angular velocity is 100 rad/s, the initial angular velocity is unknown, and the time is 6.0 s. Therefore, we need to find the initial angular velocity.

We can rearrange the formula as:

initial angular velocity = final angular velocity - (angular acceleration * time)

Since we don't have the initial angular velocity, we cannot determine the value of the angular acceleration. Therefore, none of the given options (-5 rad/s^2, -10 rad/s^2, -15 rad/s^2, -20 rad/s^2) are correct.
