Please check if my answer is reasonable. Any input is appreciated.
Q. Given a hollow and a solid cylinder of equal masses that are placed on an inclined plane. Also, both cylinders have equal radii. Which cylinder will rewach the bottom of the plane first?
Solution:
I_solid=(1/2)MR^2
I_hollow=MR^2 (fow negligible thickness cylinder)
-I about an axis is used to describe how difficult it is to induce rotational motion. Higher I means higher resistance to rotational motion, and vice versa. Therefore, the solid cylinder reaches the bottome first.
