To study damage to aircraft that collide with large birds, you design a test gun that will accelerate chicken-sized objects. The displacement of these objects along the gun barrel is given by x. What is the purpose of designing this test gun?
1) To measure the speed of the chicken-sized objects
2) To measure the force exerted on the chicken-sized objects
3) To study the damage caused by the collision of chicken-sized objects with aircraft
4) To study the trajectory of the chicken-sized objects
