Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points Feng and Isaac are riding on a merry-go- round. Feng rides on a horse at the outer rim of the circular platform, twice as far from the center of the circular platform as Isaac, who rides on an inner horse. When the merry-go-round is rotating at a constant angular speed, what is Feng’s angu- lar speed? 1. half of Isaac’s 2. impossible to determine 3. twice Isaac’s 4. the same as Isaac’s 002 (part 1 of 2) 10.0 points Consider the problem of the solid sphere rolling down an incline without slipping. The incline has an angle θ , the sphere’s length up the incline is ℓ , and its height is h . At the beginning, the sphere of mass M and radius R rests on the very top of the incline. M μ ℓ θ h What is the acceleration of the center of mass? The moment of inertia of a sphere with respect to an axis through its center is 2 5 M R 2 ....
