    Answer:

    0.131 m

    Explanation:

    Applying,

    v² = u²+2gh………………. Equation 1

    Where, v = final velocity, u = initial velocity, g = acceleration due to gravity, h =  maximum height of the object

    make h the subject of the equation

    h = (v²-u²)/2g……….. Equation 2

    From the question,

    Given: v = 0 m/s (at the maximum height), u = 1.60 m/s

    Constant: g = -9.8 m/s² (thrown up)

    Substitute these values into equation 2

    h = (0²-1.6²)/[2×(-9.8)]

    h = -2.56/-19.6

    h = 0.131 m
