$x_m=14.68" "m$

$v_i=12 " "m/s" initial velocity of object"$
$alpha=pi/4$

$x_m:"the horizontal distance"$

$g=9.81" "m/s^2$

$x_m=(v_i^2*sin 2 alpha)/g$

$2 alpha=2*pi/4=pi/2" ; "sin (pi/2)=1$

$x_m=(12^2*1)/(9,81)$

$x_m=144/(9.81)$

$x_m=14.68" "m$

A projectile is shot at an angle of pi/4 pi/4 and a velocity of 12 m/s 12 m/s. How far away will the projectile land?
