A ball is projected horizontal with a speed v from the top of a plane

1.	A ball is projected horizontal with a speed v from the top of a plane inclined at an angle45^(@) with horizontal. How far from the point of projection with the hall strike the plane?
Answer» `(v^(2))/(g)` `sqrt(2) (v^(2))/(g)` `(2v^(2))/(g)` `sqrt(2) [(2v^(2))/(g)]` ANSWER :D
