일반물리학 1 — Force and Motion-II: Problem 31

31 In Fig. 6-37, two blocks, in contact, slide down an inclined plane AC of inclination 30°. The coefficient of kinetic friction between the 2.0 kg block and the incline is \(\mu_1 = 0.20\) and that between the 4.0 kg block and the incline is \(\mu_2 = 0.30\). Find the magnitude of the acceleration.
