Content of the Lesson: Creator/Host/Writer: Dianna Cowern Producer: Laura Chernikoff Head Writer: Jeff Brock Researcher/Writer: Sophia Chen Editor: Levi Butner Exercises in this video: Problem 1: 1. You are running north-east at a speed of 4 m/s. What component of your velocity is north? How about east? Problem 2: You are kite-surfing and your kite is pulling you upwards at an angle of 60º with respect to the ocean, with a force of 1200 Newtons. What component of that force is up? How much of it is sideways, parallel to the water? Problem 3: Extra Credit: You are swimming across a river, swimming perpendicularly to the current. You can swim 1 m/s. The river has a current of 2 m/s. With respect to the shore, what is the angle of your resulting velocity vector? How fast are you swimming over the riverbed?
