A uniform hoop (I = MR2), solid disk (I = 1/2 MR2), and solidsphere (I = 2/5 MR2), each with the same mass and radius, arerolling without slipping, at the same speed on a horizontalsurface. The surface they’re rolling on then begins to angleupward. Which of the three objects rolls the least distance up theinclined plane (still assuming that the objects do not slip)?
A The question cannot be answer unless the slope of the inclinedplane is known.
B They all go the same distance
C The solid disk
D The hoop
E The solid sphere
