Reversible collision?

Classical Mechanics Level 2

A ball hits a horizontal floor at an angle of 3 0 ∘ 30^\circ and rebounds at 6 0 ∘ 60^\circ . If the ball hits the same surface at an angle of 6 0 ∘ 60^\circ , at what angle θ \theta will it rebound?

Note: All the angles are measured from the normal.

Less than 3 0 ∘ 30^\circ 3 0 ∘ 30^\circ In between 3 0 ∘ 30^\circ and 6 0 ∘ 60^\circ 6 0 ∘ 60^\circ Greater than 6 0 ∘ 60^\circ

There is energy loss in this collision and hence the gravity pulls it down more thereby increasing the angle
