11) A computational model predicts the maximum kinetic energy a roller coaster car can have given its mass, the speed at the highest point of its journey, and the height of the highest point. The mass is 250 kg, and the highest point of the journey is at 30 m, where the cart is at rest. What is its maximum kinetic energy? -112,500 J
-468,750 J
-73,500 J
- 0 J

12) Which statement provides the best description of a computational model?
-It is something that allows us to know exactly what will happen if we input enough accurate information.
-It is a simplified version of reality used to make predictions.
-It is an exact representation of reality, but on a scale we can use more easily.
-It is an individual’s guess about how things will work out.
