1. A tight rope walker is using a pole to help her maintain balance while walking across a tightrope over the Grand Canyon. She applies a force with magnitude of 100 N to a pole at a distance of 0.4 m from the center of mass of the pole (located at 50% of the pole length). The pole has a mass of 10 kg and an overall length of 1.2 m. Calculate the angular acceleration of the pole under these conditions.
