Physics

A mass m = 17 kg is pulled along a horizontal floor, with acoefficient of kinetic friction μk = 0.06, for adistance d = 5.1 m. Then the mass is continued to be pulled up africtionless incline that makes an angle θ = 28° with thehorizontal. The entire time the massless rope used to pull theblock is pulled parallel to the incline at an angle of θ = 28°(thus on the incline it is parallel to the surface) and has atension T = 34 N.

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

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

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

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

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