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?
