An aluminum block, m1 = 3.00 kg, and a copper block, m2 = 1.14 kg, are connected by a light string over a frictionless pulley. They sit on a steel surface as shown in the figure below, where θ = 45.0°. (See the table below for the appropriate coefficients of friction).
Determine the sum of the magnitudes of the forces of friction acting on the blocks.
Where is the table?
