An airplane flies eastward and always accelerates at a constant rate. At one position along its path it has a velocity of 26.1 m/s, it then flies a further distance of 43700 m and afterwards its velocity is 43.5 m/s. Find the airplane\’s acceleration and computes how much time elapses while the airplane covers that 43700 m.
Acceleration:
Elapse time:
