Halliday, Resnick & Walker — Force and Motion–II: Problem 66_GO

In Fig. 6.39, block 1 of mass \( m_1 = 2.0 \text{ kg} \) and block 2 of mass \( m_2 = 3.0 \text{ kg} \) are connected by a string of negligible mass and are initially held in place. Block 2 is on a frictionless surface tilted at \( \theta = 30^\circ \). The coefficient of kinetic friction between block 1 and the horizontal surface is 0.25. The pulley has negligible mass and friction. Once they are released, the blocks move. What then is the tension in the string?
