While dangling a hairdryer by its cord, you observe that the cord is vertical when the hairdryer is off and, once it is turned on, the hairdryer moves to the right and comes to rest when the cord makes an angle of 5o with the vertical, as shown below. In a different experiment, you determine that the same hairdryer is pushing 0.06 m3 of air through itself every two seconds. The mass of the hairdryer is 420 g. Determine the speed of the air leaving the hairdryer, vair. Assume that the mass of 1 m3 air is 1.2 kg and that the hairdryer is blowing air perpendicular to the wire.
