Part II Objective: To verify that the horizontal component of the velocity (Vx) of the projectile is constant during its motion. Procedures: 1- Open the same link: https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile- motion_en.html 2- Set the height at zero level, H=0 m as shown: Initial Values Height: 0 m Angle: 30 Speed: 17 m's Cannonball Mass 1.17 kg Diametar 0.67 m Adjust the launcher at 30° Gravity 9.81 m's Time 0.87s O Air Rosistance A Range 12.76 m Altitude Helght 3.68 m Drag Cooficiont 0.47 Range (x) 266 m Intial Speed 17 mis II O O Normel • Slow 3- Adjust the launcher at 0 4- Set the initial velocity of the projectile y at 15m/s. (you are free to select the initial velocity) 5- Fix the height (H), initial velocity (K) and the angle (0) at the above values and don't change them during this part. 6- Measure the time of flight for different horizontal distances as shown in the 30°. Table 2.
