The two blocks A and B each have a mass of 500 g. The blocks are fixed to the horizontal rods and their initial velocity is 2 m/s in the direction shown. If a couple moment of M = 0.8 N • m is applied about CD of the frame, determine the speed of the block in 4 s. The mass of the supporting frame is negligible and its free to rotate about CD.

[A].

v_{2} = 10.67 m/s

[B].

v_{2} = 23.3 m/s

[C].

v_{2} = 22.3 m/s

[D].

v_{2} = 12.67 m/s
