Question

The ball rolls down without slipping (which is at rest at a)
along ab having friction. It rolls to a maximum height hc
where bc has no friction. Kₐ, K₆ and K꜀ are kinetic energies
at a, b and c.
Which of the following is correct ?
(a) Kₐ = K꜀, hₐ = h꜀ (b) K₆ > K꜀, hₐ = h꜀
(c) K₆ > K꜀, hₐ < h꜀ (d) K₆ > K꜀, hₐ > h꜀
