Final answer:
When a constant net force is applied to an object, it causes the object to accelerate. If the force is doubled, the acceleration of the object will also double.
Step-by-step explanation:
When a constant net force is applied to an object, it causes the object to accelerate. The acceleration of an object is directly proportional to the net force acting on it. In this case, if the force is doubled, the acceleration of the object will also double.
For example, if the initial acceleration of the object is 7.0 m/s², when the force is doubled, the acceleration will be 2 times 7.0 m/s², which equals 14.0 m/s².
So, the acceleration of the object will be 14.0 m/s² if the force is doubled.
