Suppose that the numerical value of the initial speed of a rollercoaster is 12.00 m/s, the initial height is 300.0 m, and the mass of the coaster is 1000.0 kg.
1. What is the speed of the coaster at point A?
2. What is the speed of the coaster at point B?
3. What is the speed of the coaster at point C?
4. How high will it go on the last hill, which is too high to cross?
5. If we substitute a second coaster with twice the mass, what is the speed of this coaster at point A?
6. What is the speed of this coaster at point B?
7. What is the speed of this coaster at point C?
8. How high will it go on the last hill?
