If its velocity after π seconds is π£,then its displacement in the last two seconds is (A) \dfrac{2v\left( n+1\right) }{n} (B) \dfrac{v\left( n+1\right) }{n} (C) \dfrac{v\left( n-1\right) }{n} (D) \dfrac{2v\left( n-1\right) }{n} Answer : option (D) Solution : Related Previous Post A goa can travel at a speed of 8 kmhβ1 in still water on a lake. In the flowing water of a stream, it can move at 8kmh β1 relative to the water in the stream. If the stream speed is 3kmh β1 , how fast can the boat move past a tree on the shore in travelling (i) upstream (ii) downstream?
