a soccer ball is kicked 25 meter,It's maximum hight is 6 meter,Wha is its initial velocity and the time of flight

    since the range and max height are

    r = v^2 sin2θ/g = 25
    h = v^2 sin^2θ/2g = 6

    tanθ = 24/25
    so you can find the initial v.

    And of course, the height y is

    y = vt - g/2 t^2
    set y=0 to find the flight time t.
