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  104 kg and was driven by an estimated unbalanced force of about 7.23  105 N. What was the acceleration of the Lockheed SR-71?

Iassume the answer is 75 feet. inwards to outwards rather than outwards to inwards. probably be 75.hachures are stokes drawn in direction of the steepest slope. a series of short parallel lines drawn on a map to indicate topographic relief. it is actually called hachures on contour lines. the small marks in the center of the feature are called hachures.observe the picture attached
