A body is projected with velocity u from the top of building h meter high. Find the angle of projection so that it falls at farthest point.
Given, a body is projected with velocity u.
Height of the building = h
To find - angle of projection
Let the stone be projected at angle θ to make it fall at farthest point R from the foot of tower.
The equation of trajectory of body is given by,
is the required angle og projection so that the body falls at the farthest point.
