Part I: Horizontally Launched Projectiles 1. Set the initial height of the cannon to 10 m, its initial speed to 18 m/s and the angle of the cannon to be exactly 0° as per the screenshot below: Initial Values Height 10 m Angle 0 Speed 18 mis Car Mass 2000 k 100 5000 Diameter 20m Gravity 91 ma O A Resistance Aude Drag Coefficient 5 Ial 18 ms Projectile Motion PKET: 2. For a situation like the one above, what is the initial vertical velocity (viy) of the projectile be? Explain your answer. 3. Now, try to set the initial height of the cannon to 5 m, its initial speed to 25 m/s and the angle of the cannon to be exactly 0° as per the screenshot below: Initial Values Height: 5m Angle: 0 Speed: 25 m/s Car Mass 2000 kg 100 100 5000 Diameter 2.0m 0.5 Gravity 9.81 mis Air Resistance Atude Om Drag Coefficient: 0.55 14.0 m Initial Spee 25 mis O Normal O Slow PHET.: Projectile Motion Vectors Dra Lab 4.
