SUMMARY
The magnitude of the frictional force on m1, with a mass of 4.0 kg and a static friction coefficient (μs) of 0.40, is calculated using the equation Fs = μs Fn. Given m2 = 2.0 kg and an angle θ = 30°, the gravitational force acting on m1 must be determined first. The correct calculation reveals that the frictional force is not zero, contrary to initial assumptions, and should be computed accurately using the net forces acting on both masses.
