SUMMARY
The coefficient of kinetic friction between the two blocks is established as 0.30, with masses m1=2 kg, m2=3 kg, and m3=10 kg. The equations of motion derived include T2 = m3g - m3a and T1 = m1a + m1gμ, leading to the acceleration calculation a = (m3g - 2m1gμ)/(m1 + m2 + m3). The correct acceleration is determined to be approximately -5.7 m/s², aligning with the textbook answer, contrasting with an initial incorrect calculation of -6.15 m/s².
