Q8 Two solid spheres of equal radius and equal mass start at rest at the same height and move to the bottom of two different curved ramps in two different ways. In the first case (i), depicted in the left figure above, the ramp has no friction so the sphere slides without rotating. In the second case (ii), depicted in the right figure above, the sphere rolls without slipping down the ramp. In which case will the sphere have more...
