A hollow cylinder, a solid cylinder, a hollow sphere, and a solid sphere roll down a ramp without slipping,
starting from rest. The ramp is 0.25 m high. All the objects have radius 0.021 m. What are their final
speeds?
Hint: Use conservation of energy and the condition for rolling without slipping. You can look up the
formulas for the moments of inertia for each object in the textbook.
