We can solve the problem by using conservation of energy.
In fact, initially the projectile has only kinetic energy, which is given by
where m is the projectile's mass while
is its initial velocity.
At the point of maximum height, the speed of the projectile is zero, so it only has gravitational potential energy which is equal to
where g is the gravitational acceleration and h is the maximum height of the projectile.
Since the energy must be conserved, we can equalize K and U to find the value of h:
