If the blocks A and B are moving towards each other with acceleration a and b as shown in the figure, find the net acceleration of block C.
  • a)
    aiˆ - 2(a + b) ˆj
  • b)
    - (a + b) ˆj
  • c)
    aiˆ - (a + b) ˆj
  • d)
    None of these
Correct answer is option 'A'. Can you explain this answer?

If the blocks A and B are moving towards each other with acceleration ...
Since A us moving in direction of positive i^ with acceleration a, therefore block c attached to it will also have acceleration ai^. And both blocks are moving towards each other so l2 and l4 are both getting accelerated in -j^ with relative acceleration (a+b) each, so acceleration of block c in y axis is -2(a+b)j^. Therefore net acceleration= ai^- 2(a+b)j^. Hence (a) is correct option
