A certain airplane has a

speed of 290.0 km/h and is diving at

an angle of Q=30.0° below the hor-

izontal when the pilot releases a

radar decoy (Fig. 4-33). The hori-

zontal distance between the release

point and the point where the decoy

strikes the ground is d = 700 m. (a)

How long is the decoy in the air? (b)

How high was the release point?
