The distance is #=0.80m#

Resolving in the vertical direction #uarr^+#

initial velocity is #u_y=vsintheta=3*sin(1/6pi)#

At the maximum height, #v=0#

We apply the equation of motion

#v=u+at#

to calculate the time to reach the greatest height

#0=3sin(1/6pi)-g*t#

#t=3/g*sin(1/3pi)#

#=0.153s#

Resolving in the horizontal direction #rarr^+#

To find the distance where the projectile will land, we apply the equation of motion

#s=u_x*2t#

#=3cos(1/6pi)*0.153*2#

#=0.80m#
