, where 
and 
are constants and 
are respectively the horizontal and vertical distance of the projectile from the point of projection. The angle of projection 
and the maximum height attained 
are respectively given by:
Text Solution
Verified by ExpertsA
Given:
for maximum height, we should find out maximum value of 
from equation
so, for maximum value of 
Now, put value of 
from equation in quation
So, 
As we know maximum height 
from and 
and range
