You are riding in a spaceship that has no windows, radios, or other means for you to observe or measure what is outside. You wish to determine if the ship is stopped or moving at constant velocity. What should you do

give up because nothing can be done.

Explanation:

You would have to give up because you have taken on an impossible task. And nothing can be done because there is no known means available to you to measure or observe what is happening outside the spaceship. And as a result this has made it an impossible task knowing the velocity of the ship or finding out.
