Question 13 of 15

14. mark review A thick-walled hollow sphere has outside radius R₀. It rolls down an incline without slipping, and its speed at the bottom is v₀. Now the incline is waxed, so that it is practically frictionless, and the sphere is observed to slide down ( without rolling). Its speed at the bottom is observed to be 5y₀/4. Determine the radius of gyration of the hollow sphere about an axis through its center.
