After touchdown a fighter jet passes a marker on the runway at an instantaneous speed of 100 m/s and constant negative acceleration of -15 m/s2. After slowing down to 25 m/s, the pilot suddenly goes to full power to provide a new constant acceleration of 34 m/s2 for a "touch and go" takeoff. How far from the original runway marker does the plane achieve its takeoff speed of 147 m/s?
