A mass m = 17 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk = 0.06, for a distance d = 5.1 m. Then the mass is continued to be pulled up a frictionless incline that makes an angle θ = 28° 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 = 28° (thus on the incline it is parallel to the surface) and has a tension T = 34 N.

a) What is the work done by tension before the block gets to the incline?

b) What is the work done by friction as the block slides on the flat horizontal surface?

c) What is the speed of the block right before it begins to travel up the incline?

d) How far up the incline does the block travel before coming to rest?

e) What is the work done by gravity as it comes to rest?

Let's suppose we are pulling a box of mass m along a horizontal floor. All sides of the box have the same type of surface (same coefficient of friction between any side and the floor). In one case, the contact surface is much larger (first picture) and in another, it is much smaller. Will there be any difference in the force of friction? Why?
