Part C If the captain of ship A fires a missile, counts 10.0 ss on his watch, and then fires a second missile, how much time Δt will the captain of ship B measure to have passed between the firing of the two missiles? Part D The captain of ship B knows that ship A uses 2-m-long missiles. She measures the length of the first missile, once it has finished accelerating, and finds it to be only 0.872 mm long. What is the speed u of the missile, relative to ship B? Use c=3×108m/s=3×108m/s.
