Buggy , the Star Clown has special type of cannon ball called " Buggy Ball " which has the same range R on a horizontal plane for two angles of projection. If h 1 , h 2 are the greatest heights attained by the buggy ball in the two paths for the above two angles of projections , What is the value of the expression :
h 1 h 2 R

No more of this non-sense subject until college starts !

Well , you are saying that Einstein is non-sense? :(

Umm , well .. he did make life tough for me ,but I'm saying I won't be studying or solving questions from Physics .
I'll just be doing QM and Stat. Mech , that's the only part of Physics that I actually like :D

@A Former Brilliant Member – I will hit you so hard that your name would become :
Roopesh M Azhaghu ;)
Note: You must not cry afterwards. Okay?

@Swapnil Das – I never brought sir Einstein's name into the picture .In fact I told that I like QM , so how can I hate him ??
It's all Nihar's doing . It looks like he hates sir Einstein .

@A Former Brilliant Member – I commented "Well , you are saying that Einstein is non-sense? :( " . Did you see the "frown face" i.e " :( " ? Doesn't that mean I am unhappy that you are saying that Einstein is non-sense .
Then how can you comment : " It looks like he hates sir Einstein ." ? Doesn't that mean you are non - sense? @Azhaghu Roopesh M ;) :P

@Nihar Mahajan – What doesn't make sense is that you didn't read my comment properly , I had never mentioned sir Einstein , and all of a sudden you bring about him into the convo .

@A Former Brilliant Member – OK, please don't make this conversation a fight!

@Swapnil Das – Swapnil , this is neither a fight nor a conversation , its just time pass :P

@Nihar Mahajan – Oh! Nice then. i thought this conversation was then taking a serious mood! :P

By standard projectile formulae , if the angles of projection are θ 1 , θ 2 thrown with velocity v we have:
R = g v 2 sin 2 θ 1 = g v 2 sin 2 θ 2 h 1 = 2 g v 2 sin 2 θ 1 h 2 = 2 g v 2 sin 2 θ 2
Let h 1 h 2 R = λ
So we have :
λ 2 = ( 2 g v 2 sin 2 θ 1 ) ( 2 g v 2 sin 2 θ 2 ) ( g v 2 sin 2 θ 1 ) ( g v 2 sin 2 θ 2 ) ⇒ λ 2 = sin 2 θ 1 sin 2 θ 2 4 × sin 2 θ 1 . sin 2 θ 2 λ = sin 2 θ 1 sin 2 θ 2 4 × 2 × sin θ 1 . cos θ 1 × 2 . sin θ 2 . cos θ 2 ⇒ λ 2 = sin 2 θ 1 sin 2 θ 2 8 sin θ 1 sin θ 2 × 2 sin θ 2 sin θ 1 ⇒ λ 2 = 1 6 ⇒ λ = 4
