A block of mass 3.42 kg is drawn at constant speed a distance of 1.32 m along a horizontal floor by a rope exerting a constant force of magnitude 8.62 N and making an angle of 17.0 degrees above the horizontal. Compute the coefficient of friction between the block and the floor.
vertical force on block up=8.62sin17
set this equal to the horizontal force, and solve for mu
