A 5.0 kilogram block is pushed 8.0 meter up a rough 36 degree inclined plane by a horizontal force of 79 Newton. If the initial speed of the block is 2.4 m/s up the plane and a constant kinetic friction force of 24 Newton opposes the motion, determine the following:
(1) Determine the work done by the frictional force?
(2) Determine the final kinetic energy of the block?
