[" 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 so that its range on a horizontal plane is twice the greatest height attained. If g is acceleration due to gravity, then its range is
