    There’s just one step to solve this.
    Solution
    Here’s how to approach this question

    Identify the forces acting on the masses mA and mB; for mass mA, the forces are tension (T), friction (μk×N), and its weight decomposed on the incline (mA×g×sin⁡51o).

    Step 1

    SOLUTION:

    Given,

    mA=2.2kgmB=5kgμk=0.3


    For a block with mass mA,
