Two blocks of masses 11 kg and 8.0 kg are connected together by a light red string and rest on a frictionless level surface. Attached to the 8-kg mass is a light blue string, which a person uses to pull both blocks horizontally. If the two-block system accelerates at 0.5 m/s2, what is the tension in the blue string attached to the 8-kg mass?
