Apendulum is constructed from a 5.9 kg mass attached to a strong cord of length 1.6 m also attached to a ceiling. originally hanging vertically, the mass is pulled aside a small distance of 7.1 cm and released from rest. while the mass is swinging the cord exerts an almost-constant force on it. for this problem, assume the force is constant as the mass swings. how much work in j does the cord do to the mass as the mass swings a distance of 8.0 cm?
