An airplane is flying with a velocity of 248 m/s at an angle of 30.0° with the horizontal, as the drawing shows. When the altitude of the plane is 2.8 km, a flare is released from the plane. The flare hits the target on the ground. What is the angle?
What angle? The angle of the flare tyrajectory with respect to the ground when it hits?
That would be arctan(Vy/Vx)
I assumw you know how to calsulate Vy and Vx at impact.
Vy will be negative; so will the angle
