PLSS HELP An elevator lifts a total mass of 1.1x10 3 kg a distance of 40.0 m in 12.5 s. How much power does the elevator deliver?

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.
