The cars of a roller-coaster ride have a speed of 18.5 km/h as they pass over the top of the circular track. Neglect any friction and calculate their speed v when they reach the horizontal bottom position. At the top position, the radius of the circular path of their mass centers is 25 m, and all six cars have the same mass. 18.5 km/h 25 m -16.4 m
