An airplane is flying with a velocity of 250 m/s at an angle of 30.0° with the horizontal, as the drawing shows. When the altitude of the plane is 2.2 km, a flare is released from the plane. The flare hits the target on the ground. What is the angle 0? 30.0 vo m/s Path of flare Target Additional Materials Line of sight
