Two blocks of masses 20kg and 9.0kg are connected together by a light string and rest on a frictionless level surface. Attached to the 9.0kg mass is another light string which a person uses to pull both blocks horizontally. If the two block system accelerates at 0.80m/s^2, what is the tension in the second string attached to the 9.0kg mass?
