A mass m = 14.0 kg is pulled along a horizontal floor with NO friction for a distance d =8.8 m. Then the mass is pulled up an incline that makes an angle θ = 27.0° with the horizontal and has a coefficient of kinetic friction μk = 0.41. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 27.0° (thus on the incline it is parallel to the surface) and has a tension T =63.0 N.

How far up the incline does the block travel before coming to rest? (Measured along the incline.)
