A solid uniform sphere and a uniform spherical shell, both having the same mass and radius, roll without slipping down a hill that rises at an angle (theda) above the horizontal. Both spheres start from rest at the same vertical height h.
How fast is each sphere moving when it reaches the bottom of the hill?
(Make sure that you know how to derive the answer, an algebraic expression, step by step starting from basic equations!)
- Vsolid=
- Vhollow=
- Which will reach the bottom first?
