    For a thing in free fall, so that gravity is the lone force performing on it, then the computation for weight shadows from Newton's second law.

    So we will use the formula: F = ma

    Where:

    F is force net external

    M for mass

    A for acceleration

    Since the force is given already, we need to solve for the mass:

    F = MA

    1330N = M * 9.81 m/s^2

    1330N/9.81 m/s^2 = M

    M = 135.57 kg or 136 kg
