For angle θ<45,the projectile thrown at angle θ will be in the air for ashorter interval. For the smaller angle , the vertical componant (vsinθ) is smaller than that for the larger angle.

Thus,the projectile thrown at the smaller angle will not go as high into theair & will spend less time in the air before landing
