    1. The problem statement, all variables and given/known data

    need some help...

    three blocks of masses 2kg ..3kg and 7kg are kept one above the other.
    coeff of friction between 2kg and 3 kg =0.2
    coeff of friction between 3kg and 7kg=0.3
    surface between 7kg block and ground=frictionless.

    calculate accln of each block if a force equal to 10 N is applied to the 2kg block ..3kg block and 7kg block each in three different cases.

    2. Relevant equations

    3. The attempt at a solution
