OpenStudy (anonymous):

A box of weight w=2.0N accelerates down a rough plane that is inclined at an angle ϕ=30∘ above the horizontal, as shown (Figure 6) . The normal force acting on the box has a magnitude n=1.7N, the coefficient of kinetic friction between the box and the plane is μk=0.30, and the displacement d⃗ of the box is 1.8 m down the inclined plane. Part A What is the work Ww done on the box by the weight of the box?

OpenStudy (nincompoop):

that doesn't really help

OpenStudy (perl):

Fk = n* mu

OpenStudy (perl):

n = normal force (m*g)
