In the figure below, block 1 of mass
m1 = 3.0 kg
and block 2 of mass
m2 = 1.0 kg
are connected by a string of negligible mass. Block 2 is pushed by force F of magnitude 30 N and angle
θ = 20°.
The coefficient of kinetic friction between each block and the horizontal surface is 0.25. What is the tension in the string?
