    Therefore, the time it takes for the bullet to strike the ground is 0.582 seconds

    Explanation:

    h = ut + 0.5 (gt²)

    where;

    h is the height above ground = 1.66 m

    u is the initial velocity of the bullet vertically = 0

    g is the acceleration due to gravity = 9.8 m/s²

    From the equation above

    1.66 = 0*t + 0.5*9.8*t²

    1.66 = 4.9t²

    t² = 1.66/4.9 = 0.3388

    t = √0.3388

    t = 0.582 seconds

    Therefore, the time it takes for the bullet to strike the ground is 0.582 seconds
