Explanation Section 1: To determine : The x -coordinate of the center of gravity of the boomerang. Answer : The x -coordinate of the center of gravity of the boomerang is 0 m . Explanation : Given info : The angle of legs of the boomerang from the vertical axis is 40.0 ° and the length of the leg is 0.300 m . By treating the legs of the boomerang as uniform thin rods, the center of the gravity of each rod is positioned at the center of the geometric axis of the boomerang. The x component of the center of gravity of the boomerang is located at x = 0 m because of symmetry of the legs of the boomerang. Conclusion : Therefore, the x -coordinate of the center of gravity of the boomerang is 0 m . Section 2: To determine : The y -coordinate of the center of gravity of the boomerang. Answer : The y -coordinate of the center of gravity of the boomerang is − 9.64 × 10 − 2 m . Explanation : Given info : The angle of legs of the boomerang from the vertical axis is 40.0 ° and the length of the leg is 0.300 m . The y component of the center of gravity of the boomerang is located at half of the height of the boomerang by its symmetry. The formula for the y co-ordinate of the center of gravity of the boomerang is, y cm = − l sin θ 2 l is length of legs of the boomerang
