A plane flying horizontally at an altitude of mi and a speed of passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is mi away from the station.

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
