LearningAn empty cylindrical barrel is open at one end and rolls without slipping straight down a hill. The barrel has a mass of $17\mathrm{.}0$ kg$,$ a radius of $0\mathrm{.}533$ m$,$ and a length of $0\mathrm{.}800$ m$.$ The mass of the end of the barrel equals a third of the mass of its side, and the thickness of the barrel is negligible.The acceleration due to gravity is g $=9\mathrm{.}80$ m$/$s$?.$
