Task 3: /10 14 15 15 1.A 650 kg roller coaster moves through 4 hills. a) Sketch a realistic (has friction) coaster track given the following information. (justify your answers) -Hill C has slightly less than half the gravitational energy of the max total energy. -Hill A has the least total energy, -Hill D has more than half the kinetic of the max total energy. -Hill B has the most of total energy b) The coaster is initially given 450000 J of energy over 120 m of track in 5s. What is the applied force? What is the initial speed? What is the power of the coaster motor? c) What is the idealistic (no friction) speed of the coast at a height of 25m
