Physics

A mass m = 17 kg is pulled along a horizontal floor, with acoefficient of kinetic friction ?k = 0.06, for a distance d = 6.7m. Then the mass is continued to be pulled up a frictionlessincline that makes an angle ? = 33° with the horizontal. The entiretime the massless rope used to pull the block is pulled parallel tothe incline at an angle of ? = 33° (thus on the incline it isparallel to the surface) and has a tension T = 46 N.

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

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

What is the speed of the block right before it begins to travelup the incline?

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

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

During the entire process, the net work done on the blockis:
