Aplane is flying east when it drops some supplies to a designated target below. the supplies land after falling for 10 seconds. how high above the ground was the airplane when the supplies were dropped? (hint: d = 1/2gt2; g = -9.8 m/s2) question 3 options: 120 meters 490 meters 980 meters 49 meters question 4 (10 points) as the supplies fell, they traveled 650 meters horizontally. how fast were the supplies and the airplane moving forward? remember that it took 10 seconds for them to reach the ground. (hint: v = d/t) question 4 options: 65 m/s 6500 m/s 0.154 m/s 660 m/s question 5 (10 points) a projectile has a vertical component and a horizontal component. question 5 options: true false question 6 (10 points) the shape of a projectile's trajectory is an ellipse. question 6 options: true false question 7 (10 points) which of the following is not true about a vertical component? question 7 options: the vertical component of a projectile changes due to gravity. the vertical component acts the same as an object in free fall. the vertical component always equals the horizontal component. question 8 (10 points) during the course of trajectory, the horizontal component of the velocity is question 8 options: constant increasing decreasing negative
