IV. Projectile Motion and Complementary Angles Directions: Study Figure 5 and answer the questions that follow. 750 60 450 30 150 Figure 5. Ranges of projectiles launched at different angles with the same speed. Questions: 1. At what angle will the projectile have the same range when thrown at an angle of 150? 300? 2. What launch angle will have the same range as a projectile launched at 20? 3. In the absence of air resistance, at what angle should the projectile be launched to get the maximum range? 4. In a sport like Javelin throw, at what angle should you launch the spear to reach the farthest distance
