The +xdirection is “downhill.’’ Application of Newton’s second law to the x- and y-axes leads to sincos0.kNmgfmaFmgθ−=Solving these along with Eq. 6-2 (fk= μkFN) produces the following result for the pig’s downhill acceleration: ()sincos.kag=−To compute the time to slide from rest through a downhill distance A, we use Eq. 2-15: AA=+¡=vtatta02122.We denote the frictionless (k= 0) case with a prime and set up a ratio:
