    Let's use the equations for rectilinear motion. One particular equation is:

    d = v₀t + (1/2) at²

    Since it has been mentioned that the object starts from rest, then v₀ = 0. Substituting the values,

    40 m = (0) (4 s) + (1/2) (a) (4 s) ²

    Solving for a,

    a = 5 m/s²

    Therefore, the acceleration due to gravity is 5 m/s².
