    What is the Frictional Force on a Car Moving Down a 14% Incline?

    sorry i have difficulty explaining thought processes. i did (m*g*sin)/(m*g*cosθ) after eliminating the m and the g from both sides I am left with sinθ/cosθ. which is the same as tanθ Fs+Ff=Fnet=ma where Fs is the force of x so Fs = (1970)(-9.8)sinθ =-2686.88 (got something different...

    What is the Frictional Force on a Car Moving Down a 14% Incline?

    Homework Statement A 1,970-kg car is moving down a road with a slope (grade) of 14% while slowing down at a rate of 3 m/s^2. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e., down the slope)?Homework Equations ∫=μ*m*g*cosθ Fn =...
