PartA Rank the objects based on the maximum height they reach along the curved incline. Hint Al Using energy conservation As the otq'ects roll up the incline, their initial kinetic and rotational kinetic energy gets converted into gravitational potential energy. Both kinetic and rotational kinetic energy are directly proportional to mass. Thus, objects with large mass will have proportionally more energy than objects with low mass. The same is true for gravitational potential energy. Notice that when you equate the initial energy and the nal potential energy, you are equating two quantities that are both proportional to the mass. Therefore. the mass will cancel from the equation. Hint A2 Moment of inertia Objects with larger moments of inertia .' are harder to rotate. Since all of the objects are initially rotating at the same speed (since they are traveling at the same speed and have the same radius)' large- I objects will have more energy than Iow- 1 objects of equal mass. Rank from largest to smallest. To rank items as equivalent, overlap them. ANSWER: I Correct
