Exercise 6: A solid sphere and a spherical shell are on top of a hill which is 3.60m tall. They are each 4.50kg. Suppose they roll down the hill. At what speed will each sphere be moving at the bottom of the hill? Here I refer to the speed of the center of mass as in class. You also have to do the algebra, as in class, to eliminate the R and ω. Also, you have to remember that the moment of inertia of a spherical shell is (2/3)MR2. I get that the solid sphere moves at 7.01m/s.
