A person on inline skates moves with constant speed along the deck of a ship, which is moving with constant velocity and parallel to the nearby shoreline.
a) Identify 3 distinct frames of reference that could apply to the skater's motion
b) Describe the skater's motion in each reference frame (diagrams could be helpful).
Compare the total energy stored in the capacitors when they are connected to the applied potential in series and in parallel.
