    Answer:

    g = 0.4 m/s²

    Explanation:

    Given the following data;

    Height = 5 meters

    Time = 5 seconds

    To find the acceleration due to gravity (g) on the planet;

    Mathematically, the maximum height of an object is given by the formula;

    H = ½gt²

    Where;

    H is the height measured in meters.

    g is the acceleration due to gravity.

    t is time measured in seconds.

    Substituting into the formula, we have;

    5 = ½ * g * 5²

    5 = 0.5 * g * 25

    5 = 12.5 * g

    g = 5/12.5

    g = 0.4 m/s²
