    Answer: t = 10s

    Explanation:

    Assuming there's no air resistance,

    Initial velocity (u) = 0 m/s

    Acceleration by gravity (a) = 9.81 m/s^2

    Displacement (s) = 500m

    Time taken (t) = ?

    Now,

    Use formula,

    s = u*t + (1/2) * a*t^2

    s = 0*t + (1/2) * 9.81*t^2

    500 = 4.905*t^2

    t = 10s
