Newton's second law of motion is F = ma.A net force of 60 N north acts on an object with a mass of 30 kg. Use Newton's second law of motion to calculate the amount of acceleration the object will experience. Then explain how the amount of acceleration will change if the net force or the mass of the object increases.
