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?
Projectiles • A projectile is: • Examples:
Vx = • Viy= • Viy= __________ m/s
Vx • The horizontal speed is ________________ because we:
Viy • a becomes ay since • ay = __________
Equations • Vx = • Δy =
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:
