1 answer

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 $v$?
