In the figure shown, a ball without sliding on a horizontal surface. It ascends a curved track up to height h and returns. The value of h is $$h1$$ for sufficiently rough curved track to avoid sliding and is $$h2$$ for smooth curved track, then

Question

Infinity Learn · Accepted Answer

If the track is smooth (case$$ $$A), only translational kinetic energy changes to gravitational potential energy. But, if the track is rough (case$$ $$B), both translational androtational kinetic energies change to potential energy. Therefore, potential energy $$(=$$ $$mgh$$$$)$$ will be more in case B than in case A.Hence, $$h1$$>$$h2$$.

In the figure shown, a ball without sliding on a horizontal surface. It ascends a curved track up to height h and returns. The value of h is h₁ for sufficiently rough curved track to avoid sliding and is h₂ for smooth curved track, then
