The + x direction is “downhill.’’ Application of Newton’s second law to the x - and y -axes leads to sin cos 0. k N mg f ma Fm g θ −= Solving these along with Eq. 6-2 ( f k = μ k F N ) produces the following result for the pig’s downhill acceleration: () sin cos . k ag =− To compute the time to slide from rest through a downhill distance A , we use Eq. 2-15: A A =+ ¡ = vt a t t a 0 2 1 2 2 . We denote the frictionless ( k = 0) case with a prime and set up a ratio:
