Two masses of 4.25 kg each, connected by a string, slide down a ramp making an angle of 44° with the horizontal. The coefficient of kinetic friction between m1 and the ramp is 0.31. The coefficient of kinetic friction between m2 and the ramp is 0.12. Find the magnitude of the acceleration of the masses.

if they are connected by a string, ,wouldn't they accelerate the same?
force down=g*sinTheta(m1+m2)g*cosTheta(mu1*m1+mu2*M2)
Forcedown=totalmass*a
solve for a.
