Question

A ball kept on a wall is pushed horizontally with
certain velocity and allowed to move under gravity. Sucha
motion is two-dimensional motion with ball covering
displacements in both x and y-directions. But both the x & y
direction motions are independent of each other. Hence,motion in x-direction can be considered as similar to straight
line motion with no acceleration. Motion in y-direction can be
considered as free fall under gravity.
In the figure shown, ball is pushed horizontally from a
height of 19.If there is no energy loss when particle collides at point B on ground, find the maximum
height attained by the particle after it rebounds
