Ineed asap .a roller coaster ride starts with the roller coaster car being pulled to the top of the first hill with a pulley system. the car is released from the top with an initial velocity close to zero, then accelerates downward. from that first hill, the roller coaster just coasts; there is no driving force, other than gravity, to keep it going. assuming no friction, what can you say about the height of the other hills in the roller coaster ride?
