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 2.25kg and is on an incline of theta1 = 45.5 degree with coefficient of kinetic friction= .205. M2 has a mass of 5.35kg and is on an incline oftheta2 = 31.5 degree with coefficient of kinetic friction = 0.105. Find the magnitude a2 of the acceleration of M2 down the incline.
