Bode made a rocket using an empty plastic bottle and fins made out of cardboard. After partially filling the bottle with water, he
pumps air into the bottle using a pump attached to the rocket with plastic tubes. When the pressure in the bottle becomes high
enough the water gushes out and launches the rocket into the air, as shown in the diagram below.

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.
