A mass m = 16 kg is pulled along a horizontal floor with NO friction for a distance d =7.5 m. Then the mass is pulled up an incline that makes an angle θ = 33° 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 = 33° (thus on the incline it is parallel to the surface) and has a tension T =68 N.
What is the work done by friction after the block has traveled a distance x = 2.9 m up the incline? (Where x is measured along the incline.)
What is the work done by gravity after the block has traveled a distance x = 2.9 m up the incline? (Where x is measured along the incline.)
How far up the incline does the block travel before coming to rest? (Measured along the incline.)
