There is well lit room with a window and a chain is hanging from the ceiling. A man enters the room who is tall enough to reach the chains unattached end. There is a clock on the wall and nothing else in the room. The man knows his height. Find the height of the room

• height of the man +length of the chain

• let the height of chain from ceiling = x
  let the height of man = y
  the height of man's hand to reach the chain above his head=z
  then
  height of ceiling=x+y+z

• oscillate chain,calculate the timeperiod for one complete oscillation by SHM.
  put in T=2*pi*(L/G)^1/2 so,L=length of chain and L + man's height=rooms height.

• room is different from the one in which chain is hanging

• let the height of man be =6 ft
  and the length of chain would be=x
  now height of room= y
  therefore y=6+x ft

• let the height of the man be"x"...
  height of the chain from ceiling is "y"
  so obviously height of the room will be...length of chain and length of man
  i..e,,x+y
