A wave pulse travels along a rope with speed v=12 m/sv = 12 \text{ m/s}. The pulse has a width of 0.5 m0.5 \text{ m} and an amplitude of 0.3 m0.3 \text{ m}. If the rope is suddenly given a sharp downward jerk at t=0t = 0, creating an inverted pulse of the same dimensions, what is the amplitude at the point where the two pulses first completely overlap?
