A car is moving inside a vertical circular track. Its mass is m = 300.0 kg , The magnitude of the gravitational acceleration is 9.80 m/s2 . The radis of the circle is r = 40.0 m . The force diagram at four specail locations are drawn on the left side of the figure. At the bottom of the track, location 1: The normal force FN1: its magnitude is NOT automatically known. (A common mistake is to think FN is always equal to the magnitude of the weight.) Here we use a space holder for magnitude FN1. Which of the following is the correct way to write its x- and y- components of FN1? Bottom of the track, location 1, FN1, x = 0 FN1, y= - FN1 FN1, x = 0 FN1, y= FN1 FN1, x = FN1, FN1, y= 0
