Projectile (Compound) Motion lagot 15 Inhal Values Angle: 0' Apand: 5 mb Mass 17.60 kg 10 m 0.15 m 9.81 m's" A Resistance Drag Coefficient: 0.47 7.1 m Intial Speed 5 m's C Objectives: To understand the concept of projectile motion. . To identify the factors that impact the time of flight of a horizontal projectile. Background information: Projectile or compound motion occurs when an object is projected into the air near the surface of the earth. Procedure: Read Section 2.5 - Compound Motion (pg. 38 - 41) in your textbook. 1) Go to: https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion_en.html 2) Click on the "LAB" icon. Spend a few minutes and familiarize yourself with the simulation.Projectile Motion_dsl.pdf 2 / 6 TT ... 3) Set the height at 10 m. 4) Select the cannonball 5) Set the angle of the launcher 0 to zero (0) degrees. 2 6) Set the velocity of the launcher at 5.0 m/s and fire the ball. Record the time of flight at the height ] point where the ball hits the ground. [Use the blue Time/Range/Height meter to obtain the 7) Repeat with the velocities listed and complete Table 1.

How did changing the velocity of the projectile impact the time of flight? 2. How did changing the angle of launcher of the projectile impact the time of flight? 3. How did changing the height of the launcher of the projectile impact the time of flight? 4. Did adding air resistance make a difference to the time flight? 5. Based on the results of your experiment, which factors impact projectile motion?
