A shop sign, with a uniformly distributed mass m = 26 kg, h=1.5 m, w = 2 m, and d= 0.6 m, is at rest when cord AB suddenly breaks. Model AB and CD as inextensible cords with negligible masses. B ZAP! Espresso Bar NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the tension in cord CD and the acceleration of the sign's center of mass immediately after AB breaks. (Round the final answers to four decimal places. Include a minus sign if necessary.) The tension in cord CD immediately after AB bre is N. The acceleration of the sign's center of mass immediately after AB breaks is a G ) m/s.
