Question

Two spheres are rolling without slipping on a horizontal floor. They are made of different materials, but each has mass 5.00 kg and radius 0.120 m. For each the translational speed of the center of mass is 4.00 m/s. Sphere A is a uniform solid sphere and sphere B is a thin-walled, hollow sphere.

For which sphere is a greater magnitude of work required? (The spheres continue to roll without slipping as they slow down.)

For which sphere is a greater magnitude of work required? (The spheres continue to roll without slipping as they slow down.)

A greater work is required for the hollow sphere.

A greater work is required for the solid sphere.

The same work is required for the spheres.
