A 560,000 kg plane uses the 300,000 N thrust from each of its four engines to takeoff. What acceleration does the plane experience? A net force of 60 N provides an object with an acceleration of 5 m/s2. What force would be needed to provide the same object an acceleration of 3 m/s2? A force gives a 6 kg object an acceleration of 3 m/s2. What acceleration will that same force give a 20 kg object?
