A small object of mass m = 234 g slides along a track with elevated ends and a central fiat part, as shown in Fig. 13-19. The fiat part has a length L = 2.16 m. The curved portions of the track are frictionless; but in traversing the fiat part, the object loses 688 mJ of mechanical energy, due to friction. The object is released at point A, which is a height h = 1.05 m above the fiat part of the track. Where does the object finally come to rest?
