Two blocks, M1 and M2, are connected by a massless string that passes over a massless pulley. M1 has a mass of 2.25 kg and is on an incline of angle 1 = 47.5° that has a coefficient of kinetic friction 1= 0.205. M2 has a mass of 5.25 kg and is on an incline of angle 2 = 32.5° that has a coefficient of kinetic friction M2 = 0.105.

The two-block system is in motion, with block M2 sliding down the ramp.

Find the magnitude a of the acceleration of block M2. Show your answer
