    ,after t=5s and velcoity=1cm/s what would be the shape of the pulses:

    Where will the leading edge of each pulse be after 5 s? Draw a picture of each pulse and, where they overlap, stack them up like boxes. That's superposition.

    so this means number second one?
    i drew both pulses and stacked the overlaping and left the others alone.
