Answer on Question 49334, Physics, Mechanics | Kinematics | Dynamics Question: A fan blade is initially rotating at an angular speed of 48.6 rpm. It slows down and eventually comes to rest in a time of 32 seconds after turning through a total of 8.8 revolutions. Find the average angular velocity of the fan blade. Solution: By the definition of the average angular velocity: where is the average angular velocity, the time. From this formula we obtain: , t is the angular displacement and t is 2 8.8rev rad rev 1.73 . 32s s Answer: Average angular velocity of the fan blade is 1.73 rad . s https://www.AssignmentExpert.com
