    m1 = 3 kg, m2 = 2 kg
    because, coeff of friction mu = 0.4
    The friction force on 3 kg block(Ff) = mu*m1*g
    Ff =04.*3*9.8 = 117.6 N ...

    Solution Summary

    Frictional force, accelerate systems and tension on a string are computed for a pulley. With good explanations and full calculations, the problems are solved.
