    To start, define up as positive and down as negative.

    Next, Newton's Second Law:

    Net Force = ma

    We have tension pulling up and weight acting down.

    T - mg = ma

    63 N - (10 kg)(9.8 N/kg) = (10 kg) a

    63 N - 98 N = (10 kg) a

    - 35 N = (10 kg) a

    a = - 3.5 m/s²

    a = 3.5 m/s² [down]

    T = 63 = m(g-a)

    63 = 10(g-a)

    6.3 = 9.806-a

    a = 9.806-6.3 = 3.506 m/sec^2 downward

    mg - 63 = ma

    solve for a
