A ladder of length 17m rests with one end agianst a vertical wall and the other on the ground. If the lower end slips away at the rate of 1ms^(-1) , then when it is 8m away from the wall, its upper end is coming down at the rate of: a) 5/8 m/s b) 8/15 m/s c) (5pi)/8 m/s d) 8/5 m/s

A ladder 20 ft long leans against a vertical wall. The top end slides downwards at the rate of 2 ft per second. The rate at which the lower end moves on a horizontal floor when it is 12 ft from the wall is a) 8/3 b) 6/5 c) 3/2 d) 17/4

An ether (A) C_5H_12O , when heated with excess of hot HI produce two alkyl halides which on hydrolysis from compound (B) and (C), oxidation of (B) gave and acid (D), whereas odixation of (C) gave a ketone (E). Deduce the structural formula of (A),(B),(C),(D) and (E).
