A mass m=15.0 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk =0.06, for a distance d=8.5 m. Then the mass is continued to be pulled up a frictionless incline that makes an angle θ=35.0° with the horizontal. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ=35.0° (thus on the incline it is parallel to the surface) and has a tension T=45.0 N.1) What is the work done by tension before the block gets to the incline?2) What is the work done by friction as the block slides on the flat horizontal surface?
