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?
