    Force = 40 - 24 = 16N

    Force = mass / acceleration

    Acceleration = Force / mass

    Acceleration = 16 / 8

    Acceleration = 2 m/s^2

    Force = 40 - 24

    = 16N.

    Thus, Force = 16N.

    By deducing Newton's second law of motion,

    F = MA

    16 = 8A

    Thus, A = 16/8 = 2 m/s²

    Thus, the object accelerates at 2m/s²
