On a roller coaster, there is a motor driven chain that the cars attach to that pull the car up the first hill. what would eventually happen if the cars were allowed to roll down the first hill and no further mechanical energy were added?

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?

Aroller coaster track is a good example of the law of conservation of energy. use this law to explain these facts about a roller coaster track. a. the largest hill for a roller coaster track is the first hill on the track. the hills after the first are smaller and smaller. b. to get to the top of the first (highest) hill, a motor pulls the cars up to the top. after the top of the first hill, a motor is not needed to keep the cars going. c. the roller coaster car moves really fast at the bottom of a hill on the track but slows down as it moves up a hill (not including the first hill).

An 800kg roller coaster starts from top of a 45m hill with a velocity of 4m/s. the car travels to the bottom, through a loop, and continues up the next hill. the end of the roller coaster has a level surface that is 4m off the ground. assume there is no friction on the roller coaster ridea and energy is concerved. q. how tall is the hill if the roller coaster is traveling at 10m/s at the top of it? q. what will be the velocity of the roller coaster at the top of the loop?
