The height and speed of a projectile launched with a speed of vo at an angle A to the horizontal are given by: ht=votsin A-0.5gt² v(t)=√v-2v₁>sin (A)+gt² where g is the acceleration due to gravity. The projectile will strike the ground when h(t) = 0, which gives the time to hit. tit=2sin (A). Suppose that A = 30°, vo = 40 m/s, g = 9.81 m/s². Use
