Question 4 A ball made of a solid material rolls without slipping down an incline with height h = 10 m. The ball's radius is R = 0.50 m. What will be its translational speed when it reaches the bottom of the incline if it starts from rest at the very top? (If the ball is approximated as a perfectly spherical object, its moment of inertia relative to an axis through its center is I = 2/3 MR, where M is the mass, and R is the radius.) MR where M is the + 10 m L.
