    Length of hole (s) = 362.77 m (Approx)

    Explanation:

    Given:

    Time taken to hit the bottom (t) = 8.6 s

    Acceleration due to gravity (g) = 9.81 m/s²

    Find:

    Length of hole (s) = ?

    Computation:

    Initial velocity (u) = 0 m/s

    S = ut + 1/2 (gt²)

    S = (0) (8.6) + 1/2 (9.81) (8.6) (8.6)

    S = 1/2 (9.81) (8.6) (8.6)

    S = 1/2 (9.81) (8.6) (8.6)

    S = 362.7738

    Length of hole (s) = 362.77 m (Approx)
