A 500kg wagon is pushed against a wall with a spring between the wall and the wagon. The spring has a stiffness coefficient of 300 N/m. If the spring is compressed a distance of .6m and the wagon continues to apply a 55N force toward the wall, then what will the acceleration of the wagon be?

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.
