A cannon ball has a range R on a horizontal plane. If h and `h^(')` are the greatest heights in the two paths for which this is possible, then-

A cannon ball has the same range R on a horizontal plane for two angles of projection. If h_(1) and h_(2) are the greatest heights in the two paths for which this is possible then:

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

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

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

A particle is projected with a velocity v such that its range on the horizontal plane is twice the greatest height attained by it. The range of the projectile is (where g is acceleration due to gravity)
