    The initial speed doesn't matter. To reach the maximum height, you need to launch straight up ... 90 degrees above horizontal.

    90 degree

    Explanation:

    The height for the projectile motion is given by

    H = u^2 Sin^2 theta / 2g

    Height is maximum when sin theta is maximum.

    Sin theta is maximum when it's value is 1.

    So the value of theta is 90 degree.
