PASSAGE
A 10 kg crate is pushed up a 30°30° incline by a horizontal force FhF_h. The kinetic friction coefficient is μk=0.25\mu_k = 0.25. The crate moves a distance of d=6 md = 6 \text{ m} along the incline surface. Take g=9.81 m/s2g = 9.81 \text{ m/s}^2. The horizontal force magnitude is Fh=80 NF_h = 80 \text{ N}.
What is the work done by the friction force on the crate over the 6 m path along the incline?
