A person holds his outstretched arm at rest in a horizontal position. The mass of the arm is m and its length is 0.740 m.When the person releases his arm, allowing it to drop freely, it begins to rotate about the shoulder joint. Find (a) theinitial angular acceleration of the arm, and (b) the initial linear acceleration of the man’s hand. (Hint: In calculatingthe torque, assume the mass of the arm is concentrated at its midpoint. In calculating the angular acceleration, use themoment of inertia of a uniform rod of length L about one end; I = 13mL2.)
