Question

correct statements are (a), (b) and (c). How do I solve this?

8. A small block rests on flat bottom of a deep bowl that is placed on a
horizontal floor. There is no friction between the block and the bowl as
well as between the bowl and the floor. Total mass of the bowl and the
block is M. If the bowl is given a horizontal velocity by a sharp hit, the
block rises to a maximum height h sliding on the walls of the bowl.
Which of the following statements are correct?
(a) Maximum kinetic energy of the bowl is Mgh.
(b) If the bowl is lighter than the block, minimum kinetic energy of the
bowl is zero.
(c) To predict minimum kinetic energy of the bowl, we must know ratio
of the masses.
(d)To predict maximum as well as minimum kinetic energy of the bowl,
we must know ratio of the masses.
