I can't believe I didn't spot that. Tracking accuracy can be increased, however, by using more than one tracking station to measure the rockets altitude. It is true, Elon learned a lot about the fundamentals of rocket design and astrodynamics from reading books. Estimated Maximum Height: 1125 feet. According to Albert Einsteins theory of special relativity, summarized by the famous equation E=mc2, the speed of light (c) is something like a cosmic speed limit that cannot be surpassed. This looks more fun :) Will look at tommorow in more depth, brain needs its sleep at the moment. Calculations and input can be entered in either We're just talking about the first half of the ball's time in the air. the ground, between the direction the observer is facing and the reference endobj Wind farms have different impacts on the environment compared to conventional power plants, but similar concerns exist over both the noise produced by the turbine blades and the .
