The "Ring of Fire" is an area along the edge of the Pacific Ocean with many volcanoes. Most of the volcanoes are formed as a result of on tectonic plate. Which of these geological areas is where rock is recycled by one tectonic plate sliding underneath another tectonic plate?

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.
