Toolbox:
Newton's first law states that when viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.
Answer: 0 N
An object in motion will maintain its state of motion. The presence of an unbalanced force changes the velocity of the object.

Let an object be at rest initially and you push it with constant force across a friction-less surface for a time internal $\Delta t$ resulting in a final speed of $v$ for the object. Now, if you repeat the experiment with a force that is twice as large, what will be the time internal needed to reach the same final speed $v$?

Inside a horizontally moving box, a man finds that when an object is placed on a horizontal smooth table and released; it moves with an acceleration $10 m/s^2$ In this box if 1 kg body is suspended with a light string, the tension in the string in equilibrium position $(g=10 m/s^2)$
