#x_("max")=0.46 " m"#

#"rounded to the two decimal place."#

#x_("max"):"maximum value of x"#

#x_("max")=(v_i^2*sin(2 alpha))/g#

#v_i:"initial velocity ;"v_i=3" "m/s#

#alpha=pi/12" ; "2*alpha=2*pi/12=pi/6#

#sin (pi/6)=0.5#

#x_("max")=(3^2*0.5)/(9.18)#

#x_("max")=(4.5)/(9.81)#

#x_("max")=0.46 " m"#
