Can you explain this physics lab: Show steps for each thing and explain what formulas were used and how the objectives were solved...

Projectile Motion Lab Simran Dhot, Erinne Hathaway, Joshua Rojas, Hanson Zhang 1. Objectives: a. Determine initial velocity of marble fired based on its range. b. Show that there are two different angles which have the horizontal displacement. 2. Materials: a. Marble launcher with protractor b. Meter Stick Stopwatch d. Goggles 3, Data: Angles Time Range Initial Initial Initial Velocity Horizontal Vertical Velocity Velocity 15" 0.46s 3.52m. 7.91 m/'s 212 m/'s 8.18 m/'s 0.80s 5.265m 6.58 m/'s 3.8 m/'s 7.6 m/'s 0.965 5.665m 5.9 m/'s 5.9 m/'s 8.34 m/s 0.78s 4.19m 5.37 m/s 9.3 m/'s 10.73 m/'s 750 1.48s 269m 181 m/'s 6.75 m/s 6.99 m/'s 4. Conclusion: We discovered that the angle best for reaching maximum horizontal displacement was 45 degrees as it reached the farthest distance of 5.665 meters. We also found that the launcher set to 30 and 60 degrees both resulted in similar horizontal displacements, but are not exactly the same possibly because of an error in procedures, either in stopping the timer wrong or measuring incorrect or rounded distance. Additionally, we noticed the marble with the fastest horizontal velocity of 7.91 m/'s was not the one that reached the furthest and was similar to the marble with the slowest horizontal velocity which was 1 81 m/'s. The data shows that in order to gain the most range, an equal balance between horizontal and vertical velocity at 45 degrees is the best method
