Part 3: Friction and Forces If an object on an incline is not moving than the force of friction (F.) is equal or greater than the Force of Gravity (F). Force from gravity- W* sin(B) W*cos(B) Normal force w . Step 1: At what angle would a fully laden Train car not roll down the incline without assistance assuming the height is 75ml F = Force of friction = UN u. - coefficient of friction = 0.009 N = Normal force = Wcos F,-Force of gravity incline Wsinß B = Angle of incline W = weight in kg Fss = Fg ussN = Wsin ussWcos - Wsing uss = Wsing/Wcos USS=sinß/cos ustan Step 2: calculate the acceleration of a fully laden train car on an incline of 90, 60, and 30 degrees assuming the height is 75m. How long would it take for the train car to reach S0kmlh at each incline! Fs - Force of slide - FF. ma F. = JF, F, = mg
