If R is the maximum horizontal range of a particle, then the greatest height attained by it is :

If the horizontal range of a projectile be a and the maximum height attained by it is b, then prove that the velocity of projection is

Particle is projected with a velocity v so that its horizontal range twice the greatest height attained. The horizontal range is:

A particle is projected with a velocity u so that its horizontal range is twice the greatest height attained. The horizontal range is

Show that maximum horizontal range is 4 times the maximum height attained by the projectile.
