## Question:

The two blocks A and B each have a mass ${ M }_{ 0 }$. The blocks are fixed to the horizontal rods, and their initial velocity is v’ in the direction shown. If a couple moment of M is applied about shaft CD of the frame, determine the speed of the blocks at time t. The mass of the frame is negligible, and it is free to rotate about CD. Neglect the size of the blocks. Given: ${ M }_{ 0 }$ = 0.4 kg , a = 0.3 m , v’ = 2 m/s , M = 0.6 N⋅m , t = 3 s
