A slide loving pig slides down a 40° incline (Fig. 6-24) in twice the time it would take to slide down a frictionless 40° incline. What is the coefficient of kinetic friction between the pig and the slide?
F=ma ; a=(V-Vo)/t ; F=m((V-Vo)/t)
so m((V-Vo)/t) = m((V-Vo)/2t)F(friction)
m cancels V-Vo cancels t cancels which leaves 1/2F(friction) = 1
after solving for F(friction) I get 2, which is wrong, everything cancels pretty much. so I am at a loss
