To practice Problem-Solving Strategy 7.1 Rotational dynamics problems. Suppose that you are holding a pencil balanced on its point. If you release the pencil and it begins to fall, what will be the angular acceleration when it has an angle of 10.0 degrees from the vertical? What is the distance r_n between the point of application of n^vector and the axis of rotation? What is the distance r_w between the point of application of w^vector and the axis? Enter your answers in meters separated by a comma. r_n, r_w = m, m Use the information that you have gathered to find the angular acceleration. Determine whether your answer makes sense.
