Question 699: Centre of Mass and Rotational Motion

Question

For a hollow cylinder and a solid cylinder rolling without slipping on an inclined plane, then which of these reaches earlier

Accepted Answer

Solid sphere reaches the bottom first because for solid cylinder $${{{K^2}} \over {{R^2}}} = {1 \over 2}$$, and for hollow cylinder  $${{{K^2}} \over {{R^2}}} = 1$$
Acceleration down the inclined plane $$ \propto {1 \over {{{{K^2}} \over {{R^2}}}}}$$
Solid cylinder has greater acceleration, so it reaches the bottom first.
