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
