Galilean position transformation
A marker in a cyclist power-output analysis is at \(x=120\,\text{m}\) in the lab frame at \(t=8\,\text{s}\). A second frame moves at \(16\,\text{m s}^{-1}\) in the positive x-direction. Calculate \(x'\). Enter the numerical result and choose the interpretation that matches the physics meaning.
Worked practice: physics data and result
Read the physical quantities first, then calculate the result and state what it means.

Now write the response in full, in your own words — this is what the exam asks for. The AI marks it on the same moves you built above (focus, evidence, technique, judgement) and gives feedback on reasoning, evidence, and expression.
