The elapsed time is 3.5 s. Initial angular velocity Wo. +3.0 rad/s final angular velocity W.+5.0 rad/s
To find the average angular acceleration, we can use the formula:
Average angular acceleration (αavg) = (final angular velocity - initial angular velocity) / elapsed time
Plugging in the given values, we have:
αavg = (5.0 rad/s - 3.0 rad/s) / 3.5 s
Simplifying, we get:
αavg = 2.0 rad/s / 3.5 s
Therefore, the average angular acceleration is approximately 0.57 rad/s^2.
