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

    Here is the statement :
    An elevator cabin of mass 567 kg combine a mass of people inside the cabin of 180 kg.The cabin is pulled upward by a cable with a constant acceleratuon of 6 m/s².
    What is the tension T of the cable

    2. Relevant equations

    I used the second law of Newton :
    Fnet = ma
    with m = 567 + 180 = 747
    3. The attempt at a solution

    so T+ Fg = ma
    and T= ma+ mg
    so T= 11810.07 N

    IS IT CORRECT ??
