you are to design a roller coaster in which cars start from rest at a height h=26.0 m , roll down into a valley and then up a mountain. neglect friction.
a) what is the speed of the cars at the bottom of the valley?
B)if the passangers are to feel 8g at the bottom of the valley, what must be the radius R of the arc of the circle that fits the bottom of the valley?
c)the top of the next mountain is an arc of the circle of the same radius R. if the passengers are to feel 0g at the top what must be its height h?
there is a given picture, I do not know where to start.
