The equation 
<span>sets the parabola. You can find the parabola vertex as:

then
This means that the maximum height is 11.375 m and <span>a projectilereaches this height at 1.25 seconds.</span><span /><span>
</span><span>
</span><span>The projectile initially launched at time t=0, so the initial height is h(0)=2 m</span>
