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:

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-

R is the rangle on a horizontal planne for a shot with the same velocity at two differen angles of projection. If h and h' be the greatest heights attained correspoinding to these angles of projection, what is R^2 equal to ?

A particle is projected with certain velocity at two different angles of projections with respect to horizontal plane so as to have the same range 'R' ona horizontal plane. If 't_1' and 't_2' are the times taken for the two paths, then which one of the following relations is correct?

A projectile can have same range from two angles of projection with same initial speed . If h_1 and h_2 be the maximum heights, then the relation between range and two heights is
