A man runs across the roof, top of a tall building and jumps horizontally with the hope of landing on the roof of the next building which is at a lower height than the first. If his speed is 9 m/s, the (horizontal) distance between the two building is 10 m and the height difference is 9 m, will he be able to land on the next building? (Take, g =10 m/s2 )

What should be the fees for class XI and xii physics per class in Bhubaneswar?

According to me, the best fee will be the changed study pattern of the students from rote to conceptual and being able for themselves to choose what they actually want to do after 12th ( not necessarily engineering or MBBS). Thanks.
