If the initial velocity of a projectile be doubled, keeping the angle of projection same, the maximum height reached by it will

If the initial velocity of a projectile be doubled, keeping the angle of projection same, the maximum height reached by it will

In oblique projection, maximum height attained by the projectile is

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

A javelin is thrown with an initial velocity v_0 at an angle theta with the horizontal. Find the angle of projection at which the maximum height attained by the javelin is equal to the horizontal range.

If the maximum vertical height and horizontal ranges of a projectile are same, the angle of projection will be

If the maximum vertical height and horizontal ranges of a projectile are same, the angle of projection will be

If the maximum vertical height and horizontal ranges of a projectile are same, the angle of projection will be
