Until it was recently discontinued , the fastest jet plane in the skies was the Lockheed SR-71 Blackbird . However , this plane did not reach its high speeds through large acceleration . The plane had a mass of 7.7*10^ 4 kg and was driven by an estimated unbalanced force of about 7.23 * 10 ^ 5 * N What was the acceleration of the Lockheed SR- 71?
