a) A study was conducted to compare the elbow range of motion of the dominant and nondominant arms of professional baseball pitchers (Wright et al., 2006). The average maximal flexion angle for the dominant arms of professional pitchers was 130 degrees while the average extension angle was 5.5 degrees. In the nondominant arms, the average flexion angle was 135 degrees and the average extension angle was -2.4 degrees (a negative value represents elbow hyperextension). What are the totai ranges of motion for the dominant and nondominant eibows? Express your answers in degrees and radians. b} In the hammer throw, the hammer is a metal ball that is attached to a wire with a handle. The athiete extends her arms and grasps the handle and spins before releasing the hammer while trying to throw it as far as possible. The length of the wire is 119.5 cm and based on anthropometric data, a person's extended grip length is approximately 44% of their total height (Chaffin et al., 1999). The athlete is 5 feet 8 inches tall. i. If the angular velocity of the athiete is 640 degrees per second, what is the radial acceleration of the hammer head? ii. What is the tangential velocity of the hammer head? Page 2 of 3
