A net force of 30 N is applied to an object with a mass of 15 kg. The object accelerates at 2 m/s2. If half the force is applied, what happens to the acceleration?

The acceleration of an object is directly proportional to the force applied to it and ... Calculate the acceleration if you push with a 20-N horizontal force on a 2-kg ... If a 1-N net force accelerates a 1-kg mass at 1 m/s2, what is the acceleration ... 30 000 kg, in takeoff when the thrust for each of its four engines is 30 000 N?
