This is a book problem I was given to study but I'm confused on how to approach it: A mass m = 13 kg is pulled along a horizontal floor with NO friction for a distance d =8.3 m. Then the mass is pulled up an incline that makes an angle θ = 39° with the horizontal and has a coefficient of kinetic friction μk = 0.37. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 39° (thus on the incline it is parallel to the surface) and has a tension T =58 N. What is the work done by friction after the block has traveled a distance x=2.6m up the incline? The work done by gravity? I emailed my professor and he said to take the x=2.6m as the distance traveled along the ramp but I don't know what I am supposed to do with that.

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
