On a sailboat, the wind coming at you from directly ahead can't be used to push you forward. However the wind blowing sideways across the boat can be used to propel the boat forward. Relative to due north, the boat is facing in the direction of 43°, while the wind is blowing in the direction of 270°. If the wind speed is 8 m/s, how fast is the part of the wind blowing sideways across the deck (magnitude only)?
