A roller-coaster car has a mass of 1050 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius 18 m, its speed is not changing. (a) At the top of the hill, what is the normal force (using the negative sign for the downward direction) FN on the car from the track if the car's speed is v = 8.4 m/s? (b) What is FN if v = 17 m/s? Use g=9.81 m/s². (a) Number Units (b) Number i Units
