1. Projectile Motion

2. Projectile Motion
Projectile Motion – objects that are thrown or launched into the air and are subject to gravity
Use of components avoid vector multiplication
Components simplify projectile motion

3. Projectile motion is free fall with an initial horizontal velocity

5. Projectiles follow parabolic motion

7. Horizontal Projectilesvx
Δy = -½gΔt2 Δx = vxΔt g = 9.81 m/s2 Δy Δt Δx

8. The Royal Gorge in Colorado rises 321 m above the Arkansas River
The Royal Gorge in Colorado rises 321 m above the Arkansas River. Suppose you kick a little rock horizontally off the bridge. The rock hits the water such that the magnitude of its horizontal displacement is 45.0 m. Find the speed at which the rock was kicked.
