1. Horizontally shot projectiles

2. If you drop a ball straight down and throw a ball sideways at the same time from the same height, which one will hit first or will they hit at the same time?

3. Projectiles • A projectile is: • Examples:

4. Vx = • Viy= • Viy= __________ m/s

5. Vx • The horizontal speed is ________________ because we:

6. Viy • a becomes ay since • ay = __________

7. Equations • Vx = • Δy =

8. Practice Problem A cannon ball is shot off a cliff that is 9 m high. How far away from the base of a cliff will the cannon ball land if it is shot horizontally at 23 m/s? x y Sketch G: U: E:

9. Need time, 2 step problem… Part 1- solve Δt Part 2- solve Δx

10. If you drop a ball straight down and throw a ball sideways at the same time from the same height, which one will hit first or will they hit at the same time?
