Two masses of 1.50 kg each, connected by a string, slide down a ramp making an angle of 37° with the horizontal. The coefficient of kinetic friction between M1 and the ramp is 0.39. The coefficient of kinetic friction between M2 and the ramp is 0.14. Find the magnitude of the acceleration of the masses.
