Objective: Investigate the relationship between the projection angle and the height and range of the projectile. Directions: Study the diagram and answer the questions below. The paths of projectiles launched at the same speed but at different angles. The paths neglect air resistance. Questions: 1. Describe the shape of the trajectory for projectiles fired at different angles. 2. Compare the locations of the trajectory peaks in terms of maximum height, / reached. 3. Compare the horizontal distances (range) reached when they return to the elevation from which they were projected. 4. Among the trajectories of projectiles fired at angles, for the same launching velocity, which covered the greatest range (horizontal distance)? 5. Among the trajectories of projectiles fired at angles, for the same launching speed, which recorded the highest peak? lowest peak? 6. Which pairs of trajectories have ranges that are almost equal? 7. What can you do to increase the time the projectile is in the air?​

Answer:

1. The trajectory for horizontally fired projectiles along an incline is half open-down parabola and/or curve down, concave down.

1. The trajectory for horizontally fired projectiles along an incline is half open-down parabola and/or curve down, concave down.2. It's shape is curve when the point is at the center.
