Two blocks with masses M1 and M2 are connected by a massless string that passes over a massless pulley as shown. M1 has a mass of 2.25 kg and is on an incline of 49.5° with coefficient of kinetic friction ?1 = 0.205. M2 has a mass of 5.45 kg and is on an incline of 31.5° with coefficient of kinetic friction ?2 = 0.105. Find the magnitude of the acceleration of M2 down the incline.
