An 85.2kg propeller blade measures 2.23m end to end. Model the blade as a thin rod rotating about its center of mass. It's initially turning at 166rpm . Find the blade's angular momentum Find the tangential speed at the blade tip. Find the angular acceleration required to stop the blade in 12.0s Find the torque required to stop the blade in 12.0s.
