The speed of a homogenous solid sphere after rolling down an inclined

1.	The speed of a homogenous solid sphere after rolling down an inclined plane of vertical height h, from rest without sliding is
Answer» `sqrt(gh)` `sqrt(((g)/(5))gh)` `sqrt(((4)/(3))gh)` `sqrt(((10)/(7))gh)` Solution :At BOTTOMMOST point, total kinetic will be mgh. Ratio of rotational to translational kinetic ENERGY will be 2/5 `:. K_(T)=(5)/(7)mgh=(1)/(2)mv^(2)` `:.v=sqrt((10)/(7))gh`.
