Aplane designed for vertical takeoff has a mass of 7.7 ã 103 kg. find the net work done on the plane as it accelerates upward at 1.4 m/s2 through a distance of 31.0 m after starting from rest. answer in units of j.

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.
