A roller-coaster car has a mass of 500 kg when fully loaded with passengers. The car passes over a hill of radius r2 = 15.0 m, experiencing centripetal acceleration (directed toward the center). At the top of the track (point B), the car has a speed of 8.00 m/s. What is the normal force that the track exerts on the coaster at this point? {Consider Newton's law for centripetal acceleration and careful with t signs) 4,900 N 1,540 N 3,550 N 7,030 N O 2,770 N
