Ratio of rotational K.E. to rolling KE. of a solid sphere is

When a particle is performing linear SHM its KE is two times its pE at a position A and its PE is two times its KE at another position B . Find ratio of KE_(A) to KE_(B)

The KE of a freely falling body

The ratio of average translational K.E. and average rotational K.E. of a linear polyatomic molecule at temperature T is:

K.E. of an orbiting satellite is K . The minimum additional K.E. required so that it goes to infinity is
