The steel ball is suspended from the accelerating frame by the two cords A and B. The angles (they are on the inside) are both 60 degrees.

Determine the acceleration of the frame which will cause the tension in A to be twice that in B. The acceleration is going to the right and the cord A is to the right of the moving frame.

Provide your answer in m/s/s with one decimal point accuracy
