3. (Suzhou Phase 2017) As shown in Figure 10, there are four points A, B, C and D on the inclined plane, and ab=bc=cd.
Make a straight line parallel to the horizontal plane through B. If there is no inclined plane, when the ball is thrown horizontally from the O point at a speed of 2v, it will fall right below the C point of the horizontal line we drew. However, due to the restriction of the inclined plane, the ball will fall between bc on the inclined plane, so C is right and A, B and D are wrong.
So choose: C.
