The maximum height is #=2.49m#

Resolving in the vertical direction #uarr^+#

initial velocity is #u_y=vsintheta=27*sin(1/12pi)#

At the maximum height, #v=0#

We apply the equation of motion

#v^2=u^2+2as#

to calculate the greatest height

#0=(27sin(1/12pi)^2-2g*h#

#h=1/(2g)*(27sin(1/12pi))^2#

#=2.49m#
