Question

Figure (6-E6) shows two blocks in contact sliding down an inclined surface of inclination 30°. The friction coefficient between the block of mass 2.0 kg and the incline is µ1, and that between the block of mass 4.0 kg and the incline is µ2. Calculate the acceleration of 2.0 kg block if (a) µ1 = 0.20 and µ2= 0.30 , (b) µ1 = 0.30 and µ2=0.20. Take g = 10 m/s^2
