Question

A hollow smooth uniform sphere $$A$$ of mass $$m$$ rolls without sliding on a smooth horizontal surface. It collides elastically and head-on with another stationary smooth hollow sphere $$B$$ of the same mass mm and same radius. The ratio of the kinetic energy of $$B$$ to that of $$A$$ just after the collision is

Solution

The correct option is B $$1 : 1$$
The sphere is rolling on a smooth surface i.e., no energy is lost to friction and the kinetic energy of sphere A is transferred to the sphere B without any loss as the collision is head-on and elastic.
Thus, the kinetic energy of sphere A and sphere B are equal their ratio will be 1:1
