Motion in two dimensions: vectors and projectile motion
Main lesson
Launched level off a ledge
Use this for “A ball rolls off a 45 m ledge at 8 m/s. How long is it in the air, and how far out does it land?”
A boat crossing a river
Use this for “A boat heads straight across a 120 m river at 4 m/s; the current is 3 m/s. How long does it take, and how far downstream does it land?”
Components of a velocity
Use this for “A ball leaves at 15 m/s, 40° above level. What are its horizontal and vertical velocities?”
