A Regulation Basketball Has a 25 $\frac{2}{3}$ MR2 Starting from Rest, How Long Will It Take a of 0.560

Short Answer

A regulation basketball has a 25.0-cm diameter and a mass of 0.560 kg. It may be approximated as a thin spherical shell with a moment of inertia $\frac{2}{3}$ MR2. Starting from rest, how long will it take a basketball to roll without slipping 4.00 m down an incline at 30.0 $\degree$ to the horizontal?
