Homework Statement
If a dynamometer is set to move at 180 deg/s and it takes 0.18 seconds to reach that speed. What was the angular acceleration of the test arm in radians/s/s to get to that velocity? Give your answer rounded to two decimal places and do not include units in answer.
Homework Equations
angular acceleration (a) = change in angular velocity (w)/change in time (t)
a = w/t
The Attempt at a Solution
t = 0.18s
w = 180deg/s
a = ?
a = w/t
a = 180/0.18
a = 16.67
To find radians, 16.67/57.3 = 0.29 rad/s/s.
Is this correct?
Thank you for your help! :)
