A pendulum is constructed from a 4.4kg mass attached to a strong cord of length 1.2m also attached to a ceiling.Originally hanging vertically, the mass is pulled aside a small distance of 7.7cm and released from rest.While the mass is swinging the cord exerts an almost-constant force on it.For this problem, assume the forceisconstant as the mass swings.How much work in J does the cord do tothe mass as the mass swings a distance of 8.0 cm?
