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?

• physics -

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
