In Figure, block 1 of mass $$m_1 = 2.0$$ kg and block 2 of mass $$m_2 = 1.0$$ kg are connected by a
string of negligible mass. Block 2 is
pushed by the force of magnitude $$20 \, N$$, and angle $$\theta 35^\circ$$. The coefficient
of kinetic friction between each block and the horizontal surface is $$0.20$$. What is the tension in the string?
