Where does the United States stand in its use of renewable energy compared to the rest of the world? What is the projected goal for the future for renewable energy use?​

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.

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.

Acar of mass 800kg is moving at a speed of 2.2m/s.
