For Horizontally Launched Projectiles: Raise the launch height to about 50 meters and adjust the launch angle to 0 degrees. Conduct several trials to answer the following questions. 1. Describe the path or trajectory of the projectile? Can you write down a mathematical equation to describe it?
2. During the course of a trajectory, is the horizontal component of the velocity a constant or a changing value? If it is a changing value, then describe its changes (increasing, decreasing, or remains constant).
3. During the course of a trajectory, is the vertical component of the velocity a constant or a changing value? . If it is a changing value, then describe its changes (increasing, decreasing, or remains constant).
