Frames: 234 10 Time: 3.9000s 15 Frame Rate: 60fps 20 RESET LOCK 25 30 35 40 45 50 1. Here is some background information about the roller coaster that can be helpful: • the length of the entire rollercoaster train is 19.5 m • the lead car is 3.4 m long • the other 5 cars are 2.7 m long • the mass of each car is 1040 kg • each car can hold up to six passengers 2. Compare the mechanical energy of this roller coaster at the top to the mechanical energy at the bottom of the hill. Hint: Does the entire mass of the train roll freely, starting from rest, at the very top of the hill? в I U E E E E O D fx
