A pistol that fires a signal flare gives the flare an initial speed (muzzle speed) of 185 m/s.
(a) If the flare is fired at an angle of 55° above the horizontal on the level salt flats of Utah, what is its horizontal range? You can ignore air resistance. (b) If the flare is fired at the same angle over the flat Sea of Tranquility on the moon, where g = 1.6 m/s2, what is its horizontal range? I am just going blank i tried solving for range but am lost

Thanks i finaly got it it took me a while
This is what i did 185*sin55 =V(ertical speed) V/g = T(ime to stop vertically) T*2=total time 185*cos55 = v(horizontal speed) t*v=R(horizontal range) I did the same for the moon g = 1.6 Thanks
