A designer decides to create a new roller coaster, and begins by creating a scale model of her idea. For the model, she has a car of mass 0.88 kg be pulled up to the top of a hill, which has a height of 3.0 m. The car is launched with an initial speed vo = 1.1 m/s. Point A is located 2.6 m above the lowest point of the track, and is also the top of an arc that has a radius of 1.2 m.
