In the arrangement shown in figure, m_(A) = 1 kg and m_(B) = 2 kg, while all the pulleys and strings are massless and frictionless. At t = 0, a force F = 10 t starts acting over central pulley in vertically upward direction. If the velocity of A is x xx 10 m//s when B loses contact with floor, find x.

1.	In the arrangement shown in figure, m_(A) = 1 kg and m_(B) = 2 kg, while all the pulleys and strings are massless and frictionless. At t = 0, a force F = 10 t starts acting over central pulley in vertically upward direction. If the velocity of A is x xx 10 m//s when B loses contact with floor, find x.
