Suppose that in the situation shown in Figure 6.2, a third ruler is affixed to some device (not shown) that moves to the right along the track at a speed of \(2.0 \mathrm{~mm} /\) frame. If in the Earth reference frame cart 2 again moves at \(+3.6 \mathrm{~mm} /\) frame and cart 1 is again at rest, what are the cart velocities according to an observer moving along with ruler C?
