SUMMARY
The angular acceleration of the test arm is calculated to be 0.29 rad/s² when a dynamometer reaches a speed of 180 degrees per second in 0.18 seconds. The formula used is angular acceleration (a) = change in angular velocity (w) / change in time (t), leading to a calculation of a = 180 deg/s / 0.18 s, which equals 16.67 deg/s². Converting degrees to radians using the factor of 57.3 results in an angular acceleration of 0.29 rad/s². The calculations presented are confirmed as correct by multiple participants in the discussion.
