A solid sphere rolls in released from rest and rolls down an incline plane, which is 2.0 m long and inclined at a 30° angle from the horizontal. (a) Find its speed at the bottom of the incline. (Remember that the kinetic energy in rolling motion is the translational kinetic energy ½ Mv2 of the center, plus the rotational K.E. ½ Iω2 about the center. Also remember that v = ωr if the sphere rolls without slipping.) (b) Find the...

Darcel and Chandra are sitting in the park after physics class, and they notice some children rolling various objects down a slight incline in the sidewalk. Darcel is curious how the masses and shapes of the objects affect their motion, and Chandra says that it might be fun to think about the energy of motion associated with rolling objects. The friends decide to use the simulation to explore the motion and energies of various objects rolling down an incline. They...

Help!!! Please Two objects roll down an incline: a solid sphere (I = 2/5 MR^2) and a thin hoop (I = 1/2 MR^2). If each has the same mass and the same radius, explain how you would determine which one would reach the bottom faster. Consider conservation of energy as the object rolls. What types of energy does the object have at the top and at the bottom of the incline?
