Two small identical blocks A and B are kept on smooth horiontal surface(inextensible) string of length √2L at time t=0 the block A is at rest at x=0 and block B is at x=L moving towards +y axis with velocity v.

Q.17 Velocity of block A after t=200L/v is:
(A) vj
(B)vi
(C)v/2i+v/2j
(D)-v/2i+v/2j

i think this is wat the question is::

Two small indentical blocks A and B are kept on smooth horizontal surface (inextensible) string of length √2L .At time t=0 the block A is at rest at x=0 and the block B is at x=L moving with speed v in forward +y direction.

15. The coordinates of block A at time T=2L/v is

16. Veolcity of the block B after time t = 2L/v

17. Velocity of block A after time t= 200L/v ??? or is it 2L/v???

it is 200l/v ,the rest is same
