Question
An 8.00kg package in a mail-sorting room slides 2.00m down achute that is inclined at 53.0degrees below the horizontal. Thecoefficient of kinetic friction between the package and the chute'ssurface is 0.400. Calculate the work done on the package by friction. Calculate the work done on the package by gravity. Calculate the work done on the package by the normalforce. What is the net work done on the package?

Calculate the work done on the package by the normalforce. What is the net work done on the package?Explanation / Answer
mass m = 8 kg distance S = 2 m angle = 53 degrees The coefficient of kinetic friction between the package andthe chute's surface is = 0.400. (a). the work done on the package by friction = -mg cos * S w =- 37.74 J (b). the work done on the package by gravity w ' = mg sin * S = 125.22 J (c) the work done on the package by the normal force w "= 0 J (d). the net work done on the package = w + w ' + w " = 87.48 J (a). the work done on the package by friction = -mg cos * S w =- 37.74 J (b). the work done on the package by gravity w ' = mg sin * S = 125.22 J (c) the work done on the package by the normal force w "= 0 J (d). the net work done on the package = w + w ' + w " = 87.48 JRelated Questions
