A ball is thrown from a point at a distance 40 m from a wall of height 15 m . It just clears the wall and then attains maximum height. Find the maximum height the angle of projection is 45^(@) .

Maximum height attained from the point of projection is:

Maximum height attained from the point of projection is:

The projectile attains maximum height when it is projected at an angle of

A ball is thrown from the ground towards a wall of height h at a distance d_(1) such that it just clears the wall and falls at a distance d_(2) on the other side of the wall.If angle of projection is 45^(0) ,find h in terms of d_(1) and d_(2) .

A body projected in vertical direction attains maximum height 50 m . Find its velocity at 25 m .height

What is the angle of projection for attaining maximum vertical height ?
